Our Advanced Cholesterol & Cardiovascular Risk Blood Test goes beyond a standard lipid profile by adding Apolipoprotein B (ApoB), one of the most powerful and clinically recognised markers of cardiovascular risk available. Analysed in our own CQC-regulated London laboratory, results are returned within 24 to 48 hours of sample receipt. What is ApoB and why does it matter? Apolipoprotein B is the protein that coats every atherogenic particle (promoting the buildup of fatty plaque that clogs and hardens your arteries) in the bloodstream, including LDL, VLDL, and IDL. Each of these particles carries exactly one ApoB molecule, which means an ApoB measurement directly counts the number of harmful particles circulating in your blood rather than just estimating their cholesterol content. Research consistently shows that ApoB is a stronger predictor of cardiovascular events than LDL cholesterol alone, particularly in people with normal or borderline LDL who may otherwise be told their cholesterol is fine. Beyond Standard NHS Testing A routine NHS lipid profile measures total cholesterol, LDL, HDL, and triglycerides, which remain the foundation of cardiovascular risk assessment in primary care. However, NICE lipid guidelines (NG238, updated 2023) acknowledge Apolipoprotein B as a clinically valid alternative to non-HDL cholesterol, particularly in situations where standard markers may be less reliable, such as in people with elevated triglycerides or those already on statin therapy. Statins are highly effective at reducing LDL cholesterol, but research shows that particle burden, as measured by ApoB, does not always fall in line with LDL, meaning some individuals on statins may still carry an elevated cardiovascular risk that a standard lipid profile would not detect. By including ApoB alongside a full lipid profile, this test goes beyond routine NHS provision and brings you closer to the level of cardiovascular risk assessment recommended by international cardiology bodies such as the European Society of Cardiology, giving you a more complete and actionable picture of your heart health. Who Should Take This Test? This test is particularly valuable for anyone with a family history of heart disease or early cardiovascular events; those on statins who want to confirm their treatment is reducing particle number as well as cholesterol; people with normal LDL but persistent cardiovascular risk factors such as diabetes, obesity, or metabolic syndrome; and anyone who wants the most comprehensive and clinically advanced picture of their heart health available from a home test. FAQs What is ApoB and how is it different from LDL? LDL cholesterol measures the amount of cholesterol carried inside LDL particles, but does not tell you how many particles are present. ApoB measures the actual number of atherogenic particles directly, as each one carries exactly one ApoB protein. Two people can have the same LDL cholesterol reading but very different particle counts, and it is the particle count that drives plaque formation and cardiovascular risk. ApoB gives a more accurate and actionable picture, particularly when LDL appears normal. Why is ApoB considered a better cardiovascular risk marker than LDL? Multiple large-scale studies have shown that ApoB predicts cardiovascular events more accurately than LDL, particularly in people with metabolic syndrome, diabetes, or those already on statin therapy. Many international cardiology guidelines now recommend ApoB as the preferred marker for assessing and managing cardiovascular risk. Can I have high cardiovascular risk even if my LDL is normal? Yes. This is one of the most important reasons to measure ApoB. It is possible to have a normal or even low LDL while carrying a high number of small, dense atherogenic particles, a pattern that significantly increases risk. ApoB captures this hidden risk that a standard cholesterol test would miss. Do I need to fast before this test? Yes. We recommend fasting for 10 to 12 hours before collection, taking water only. This is particularly important for triglyceride accuracy. Collecting your sample first thing in the morning before breakfast is the most practical way to meet this requirement. Can I take this test if I am on statins? Yes, and it is particularly useful if you are. Statins reduce LDL effectively but their impact on particle number varies between individuals. ApoB is the most reliable way to confirm whether your treatment is adequately reducing cardiovascular risk, not just lowering the cholesterol figure. How quickly will I receive my results? Results are returned within 24 to 48 hours of your sample being received by our laboratory. You will receive a quantitative report with your actual figures, reference ranges, and remarks for any values outside the normal range. Frequently Asked Questions Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. It is not sent to a third-party lab. Most samples are reported the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

Check seven liver function biomarkers with an at-home finger-prick blood test, analysed in our own CQC-regulated laboratory in London. Your numerical report shows each result against its reference range, with notes on any result outside it, and is reviewed by a UK-registered doctor. Biomarkers included ALT (alanine aminotransferase): an enzyme found mainly in liver cells AST (aspartate aminotransferase): an enzyme found in the liver and other tissues, including muscle GGT (gamma-glutamyl transferase): an enzyme that can be affected by alcohol and some medicines Bilirubin (total): a pigment made when red blood cells are broken down and cleared by the liver Albumin: a protein made by the liver Total protein: the total amount of protein in your blood Globulin Who this test is for People advised by a healthcare professional to check their liver function People taking long-term medicines that need liver monitoring People living with a liver condition, or with diabetes, who have been advised to keep an eye on their liver blood tests People who want to check their results after cutting down on alcohol People who train hard or take supplements. Read our guide to training, fitness and liver health. Liver blood tests show how your liver is working at the time of the sample. They can't diagnose a specific liver condition on their own. Results can also be affected by intense exercise, some medicines and recent alcohol. If you have yellowing of the skin or eyes, seek prompt medical advice rather than waiting for a postal test. How to prepare Avoid alcohol for 24–48 hours and hard exercise for 48 hours before collecting your sample, as both can raise some liver enzymes. Keep taking any prescribed medicines as normal, and note them on your request form. Follow the collection instructions in your kit and post your sample the same day, Monday to Thursday. Your results Most samples are analysed the same day they arrive at our laboratory. Every result is reviewed by a UK-registered doctor, and your PDF report is emailed to you, usually within 1–3 working days of your sample arriving. What's included Everything you need to collect your sample at home: lancets, collection tube, request form, alcohol wipes, plasters, full instructions and a prepaid return envelope. Read more about liver blood tests and what your results mean Frequently Asked Questions Can this test tell me if I have fatty liver disease? Not on its own. Liver enzymes can be normal in fatty liver disease, and raised for many other reasons. Diagnosis needs a clinical assessment, which may include a scan. If you're concerned, speak to your GP. Do I need to fast? No, you don't need to fast for this test. Avoiding alcohol and hard exercise beforehand gives the most useful result. Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. Most samples are analysed the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

This thyroid test kit measures TSH, Free T4 and Free T3 from a finger-prick sample you collect at home. It's analysed in our own CQC-regulated laboratory in London, and every result is reviewed by a UK-registered doctor. Biomarkers included TSH (thyroid-stimulating hormone): made by the pituitary gland to control your thyroid. It's the main marker used to check thyroid function. Free T4 (free thyroxine): the main hormone made by the thyroid Free T3 (free triiodothyronine): the active form of thyroid hormone Looking at all three together helps show whether your thyroid may be underactive or overactive, and how well treatment is working if you're already on it. Who this test is for People with symptoms that can be linked to the thyroid, such as tiredness, feeling cold or hot, weight change, low mood or hair thinning People taking levothyroxine who want to check their levels. Read our guide to thyroid blood tests on levothyroxine. People with a family history of thyroid problems, or who have had a thyroid problem during or after pregnancy These symptoms have many causes, and a single result can't diagnose a thyroid condition. Don't stop or change thyroid medicine based on your result without speaking to your prescriber. Read more about how the thyroid works. How to prepare Collect your sample in the morning, at a similar time each time you test. If you take levothyroxine, collect your sample before your morning dose. Stop biotin (vitamin B7) supplements for at least 72 hours beforehand. Biotin is common in hair and nail supplements and can affect thyroid results. Don't test while you're acutely unwell, and post your sample the same day, Monday to Thursday. Your results Most samples are analysed the same day they arrive at our laboratory. Every result is reviewed by a UK-registered doctor, and your PDF report is emailed to you, usually within 1–3 working days of your sample arriving. Frequently Asked Questions Can I test my thyroid at home? Yes. You collect a small finger-prick sample at home and post it to our laboratory in the prepaid envelope. We measure TSH, Free T4 and Free T3 and email you a doctor-reviewed report. How often should I test if I'm on levothyroxine? UK guidance (NICE NG145) suggests testing about 6 weeks after a dose change, every 3 months until your levels are stable, and then once a year. Your GP may advise differently. Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. Most samples are analysed the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

Measure your cortisol level with an at-home cortisol blood test kit. Collect a finger-prick sample and return it using the included prepaid envelope for analysis at our own CQC-regulated laboratory in London.Your report shows your measured cortisol level alongside laboratory reference ranges. Most samples are analysed the same day they reach our laboratory, and your report is then available in your secure online portal.What does the cortisol blood test measure?This test measures the cortisol level in your blood sample. Cortisol is a hormone produced by the adrenal glands and is involved in the body's stress response and other essential functions.The result is a snapshot at the time of sampling, not a complete assessment of stress or adrenal function. Collection time and your individual circumstances matter when interpreting the result.Is this test right for you?If you want to measure your cortisol level, this kit offers at-home sample collection with laboratory analysis. If you are investigating persistent fatigue, sleep difficulties, weight changes or other symptoms, speak with a healthcare professional about whether cortisol testing is appropriate. These symptoms can have many possible causes.A single cortisol result cannot diagnose the cause of symptoms, measure how stressed you feel, or diagnose or rule out conditions such as Cushing's syndrome or Addison's disease on its own. Further assessment and different tests may be needed.What is included? At-home finger-prick blood sample collection kit Prepaid sample return envelope UK laboratory analysis A results report with laboratory reference ranges and medical feedback Secure online access to your results How it works Order your cortisol blood test kit. Read the enclosed instructions before collecting your sample. Collect your finger-prick blood sample early in the morning, between 6:00 am and 10:00 am, while fasting, following the test-specific instructions. Return your sample using the prepaid envelope. View your report in your secure online portal, once your sample has been analysed (most are analysed the same day they reach our laboratory). Why does sampling time matter?Cortisol levels naturally change throughout the day. Follow the collection instructions supplied with your kit and record your sampling time as instructed. If you work shifts or are unsure about preparation or timing, seek guidance before collecting your sample.How can I test my cortisol levels at home? You can measure cortisol at home with a finger-prick blood sample, collected in the morning and posted to our laboratory. Cortisol can also be measured in saliva or urine. These tests answer different questions and are not interchangeable with a blood measurement. If a healthcare professional has asked for a specific type of cortisol test, follow their advice.Can medicines affect the result?Medicines can affect cortisol levels or how results are interpreted. Do not stop or change prescribed medicines to take this test unless advised by your prescriber. Ask a healthcare professional if you are unsure whether testing is suitable for you.Understanding your resultsYour report presents your measured level with laboratory reference ranges and medical feedback. Results should be interpreted alongside your symptoms, sampling time, medicines and medical history.If your result is outside the reference range, or symptoms persist even when your result is within range, discuss the report with your GP or another qualified healthcare professional.Does this replace medical care?No. This is a private laboratory testing service, not a diagnosis or treatment plan. Do not delay medical assessment while waiting for a kit or results. If you feel acutely unwell, seek medical care rather than relying on a home test. Frequently Asked Questions Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. It is not sent to a third-party lab. Most samples are reported the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

Check your testosterone and the protein that carries it with an at-home finger-prick blood test, analysed in our own CQC-regulated laboratory in London. Your numerical report shows each result against its reference range and is reviewed by a UK-registered doctor. Biomarkers included Total testosterone: all the testosterone in your blood SHBG (sex hormone-binding globulin): the protein that binds testosterone and controls how much is available to your body Free testosterone (calculated): the unbound fraction, calculated from total testosterone and SHBG Free androgen index (FAI): a ratio of total testosterone to SHBG Looking at testosterone and SHBG together matters. If SHBG is high or low, total testosterone alone can give a misleading picture. Who this test is for Men with symptoms that can be linked to low testosterone, such as low sex drive, erection problems, fewer morning erections, tiredness, low mood or loss of muscle strength Men who want a baseline result to compare with in future Men who have been advised by a healthcare professional to check their testosterone These symptoms have many possible causes, and a single result can't diagnose low testosterone. UK guidance recommends a repeat morning test before any diagnosis. Weight, sleep, alcohol, some medicines and recent illness can all lower testosterone. If you're already on testosterone therapy, see our TRT blood test panel instead. How to prepare Collect your sample in the morning, ideally between 7am and 11am, when testosterone is at its highest. Avoid hard exercise for 24 hours beforehand, and don't test while you're unwell. Stop biotin (vitamin B7) supplements for at least 72 hours before collecting your sample. Follow the collection instructions in your kit and post your sample the same day, Monday to Thursday. Your results Most samples are analysed the same day they arrive at our laboratory. Every result is reviewed by a UK-registered doctor, and your PDF report is emailed to you, usually within 1–3 working days of your sample arriving. What's included Everything you need to collect your sample at home: lancets, collection tube, request form, alcohol wipes, plasters, full instructions and a prepaid return envelope. Read more What is the difference between testosterone and free testosterone? Understanding free testosterone Testosterone deficiency syndrome Frequently Asked Questions What time of day should I take a testosterone test? In the morning, ideally between 7am and 11am. Testosterone is highest in the morning and falls during the day, so an afternoon sample can look lower than it really is. Do I need to fast? Fasting isn't essential for this test, but eating can slightly lower testosterone, so testing before breakfast gives the most comparable result over time. Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. Most samples are analysed the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

Monitor testosterone replacement therapy (TRT) at home with one finger-prick blood test. This panel checks your hormones alongside cholesterol, liver and kidney markers. Post your sample in the prepaid envelope to our own CQC-regulated laboratory in London, where most samples are analysed the same day they arrive. Your report shows each result against laboratory reference ranges, with remarks for any result outside the range. Every result is reviewed by a UK-registered doctor before it is emailed to you. What does this test measure? Hormones Total testosterone and free testosterone SHBG (sex hormone-binding globulin) and Free Androgen Index (FAI) Oestradiol LH and FSH Cholesterol Total cholesterol, LDL, HDL and triglycerides Liver ALT, GGT, total bilirubin, albumin and total protein Kidney Urea, creatinine and uric acid Other markers Calcium, amylase and high-sensitivity CRP (hs-CRP) Complete your TRT safety checks UK guidance (British Society for Sexual Medicine) also recommends checking haematocrit and PSA during TRT. These are not included in this panel. Add our blood count and PSA test to your order for the full set of recommended checks. How often should I test on TRT? UK guidance generally recommends checks at 3, 6 and 12 months after starting treatment, then once a year, and again after any change to your dose or preparation. Your prescriber will advise on your own schedule. Read our full guide to TRT monitoring blood tests. When should I take my sample? Testosterone gel: usually 2–6 hours after applying. Wash both hands thoroughly first and prick a finger on the hand you did not use to apply the gel, as gel on the skin can give a falsely high result. Injections: usually just before your next injection. Always follow your prescriber's advice on timing, and the preparation instructions supplied with your kit. Frequently asked questions Who is this test for? Men on TRT who need regular monitoring, men adjusting their dose or preparation under the guidance of a prescriber, and men who want a broad picture of their hormone and general health markers. Should I change my TRT dose based on my results? No. Share your report with your prescriber, who will decide whether any change is needed. Do not stop or change TRT without medical advice. Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. It is not sent to a third-party lab. Most samples are analysed the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

Measure FSH, LH, oestradiol, progesterone, prolactin and testosterone with an at-home finger-prick blood test. Includes prepaid sample return and UK laboratory analysis, with a numerical report showing your levels and reference ranges.As featured in an article by the Evening Standard.The Female Hormone Test Kit measures six hormones. Collect a finger-prick blood sample at home and return it using the included prepaid envelope for analysis at our own CQC-regulated laboratory in London.Every result is reviewed by a UK-registered doctor before it is sent to you.Your results are delivered securely by email, with measured levels, laboratory reference ranges and clinical remarks for results outside those ranges. Most samples are analysed the same day they reach our laboratory.What does the test measure? Follicle-stimulating hormone (FSH) Luteinising hormone (LH) Oestradiol (a form of oestrogen) Progesterone Prolactin Testosterone Your results provide a snapshot of your hormone levels at the time of sampling. They can support a discussion with a healthcare professional, but cannot diagnose the cause of symptoms on their own.Is this the right test for you?If you are exploring concerns such as changes to your periods, energy or mood, it is important to choose a test that fits the question you want answered. These symptoms can have many causes, not just hormonal changes.Female Hormone Profile or Menopause/Perimenopause Panel?Both panels measure FSH, LH and oestradiol. The difference is the additional markers: This Female Hormone Profile: also measures progesterone, prolactin and testosterone. It does not include thyroid markers. Our Menopause/Perimenopause Hormone Panel: also measures TSH and Free T4, two thyroid markers. It does not include progesterone, prolactin or testosterone. Choose based on the markers you need assessed, rather than the number of tests included. Neither panel diagnoses the cause of symptoms on its own. If you are unsure which is appropriate, speak with a healthcare professional before ordering.When should you collect your sample? Hormone levels change throughout the menstrual cycle, so timing affects how your results are interpreted. Regular periods: collect your sample on day 2–5 of your cycle (day 1 is the first day of your period), before 10:00 am. This is the standard time for assessing FSH, LH and oestradiol. Checking for ovulation: progesterone is best measured about 7 days before your next expected period (around day 21 of a 28-day cycle). At day 2–5, a low progesterone result is expected. Irregular or no periods: you can collect your sample on any day, in the morning. Please note your cycle day on your request form so your results can be reviewed against the right reference ranges. If you are unsure when to test, seek guidance before collecting your sample.Contraception, HRT and other medicinesHormonal contraception, HRT and other medicines can affect hormone levels and how results are interpreted.Do not stop or change prescribed medication to take this test unless advised by your prescriber.

Measure your prostate-specific antigen (PSA) level with an at-home finger-prick blood test, analysed in our own CQC-regulated laboratory in London. You receive a numerical report showing your PSA level against an age-related reference range, reviewed by a UK-registered doctor. PSA is a protein made by the prostate gland. A PSA result on its own cannot diagnose prostate cancer. A raised level can have other causes, and a level within range does not rule cancer out. We recommend discussing the benefits and limitations of PSA testing with your GP before you test. Who this test is for Men aged 50 and over who have decided, after weighing up the pros and cons, that they would like a PSA test. In the UK, men in this age group can ask their GP for one. Men at higher risk who are considering testing from 45, such as Black men or men whose father or brother had prostate cancer. Men who have been advised by a healthcare professional to repeat or monitor their PSA level. If you have symptoms, such as needing to urinate more often (especially at night), difficulty starting or a weak flow, or a feeling that your bladder hasn't fully emptied, speak to your GP rather than relying on a home test. Seek urgent medical advice if you have blood in your urine or semen, or new bone or back pain. What can raise PSA? PSA can be higher than expected for reasons other than cancer, including: An enlarged prostate (benign prostatic enlargement), which is common with age Prostatitis or a urinary tract infection Recent ejaculation or vigorous exercise, especially cycling Recent prostate procedures, such as a biopsy Some medicines lower PSA. Finasteride and dutasteride can roughly halve the result, so tell your doctor if you take either of them. How to prepare Avoid ejaculation and vigorous exercise (including cycling) for 48 hours before collecting your sample. Don't test if you have a urinary infection. Wait until it has been treated and you have recovered, and ask your GP how long to wait. Don't test within 6 weeks of a prostate biopsy or procedure unless your doctor advises it. Follow the collection instructions in your kit and post your sample the same day, Monday to Thursday. Your results Most samples are analysed the same day they arrive at our laboratory. Every result is reviewed by a UK-registered doctor, and your PDF report is emailed to you, usually within 1–3 working days of your sample arriving. If your result is outside the expected range for your age, your report will recommend that you speak to your GP. What's included Everything you need to collect your sample at home: lancets, collection tube, request form, alcohol wipes, plasters, full instructions and a prepaid return envelope. Frequently Asked Questions What is a normal PSA level? PSA naturally rises with age, so there isn't one "normal" number. Your report shows your result against an age-related reference range. A result above that range doesn't mean you have cancer, but it does mean you should speak to your GP, who may repeat the test or arrange further checks. Do I need to avoid exercise or sex before a PSA test? Yes. Ejaculation and vigorous exercise, especially cycling, can temporarily raise PSA. Avoid both for 48 hours before collecting your sample. Is a finger-prick PSA test reliable? Your sample is analysed on professional laboratory analysers in our CQC-regulated laboratory, and we take part in external quality assessment schemes. Following the collection instructions carefully gives the best sample. As with any PSA test, your result should be interpreted alongside your symptoms and medical history. Can a PSA test diagnose prostate cancer? No. PSA is one piece of information. Diagnosis needs a clinical assessment, which may include an examination, an MRI scan and sometimes a biopsy. Your GP can explain the next steps if your result is raised. Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. Most samples are analysed the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

Noticing hair thinning, more shedding than usual or brittle nails? This at-home finger-prick blood test checks six markers that are commonly looked at when hair changes, covering iron stores, two nutrients and thyroid function. Your sample is analysed in our own CQC-regulated laboratory in London, and every result is reviewed by a UK-registered doctor. Biomarkers included Ferritin: your body's iron stores. Low iron stores are one of the most common findings in people with hair shedding. Read more about iron deficiency and hair loss. Vitamin D: often low in the UK, especially in autumn and winter Folate: a B vitamin needed to make new cells TSH (thyroid-stimulating hormone): the main screening marker for thyroid function Free T4 and Free T3: the thyroid hormones in your blood. Both an underactive and an overactive thyroid can affect hair. This test does not include vitamin B12. Who this test is for Adults noticing hair thinning, increased shedding or brittle nails People with heavy periods, a plant-based diet or a history of low iron People who want to check their thyroid function alongside their iron and nutrient levels Hair loss has many causes that a blood test can't show, including inherited pattern hair loss, shedding after illness, stress, surgery or childbirth, and alopecia areata. A normal result doesn't mean nothing is wrong, and a result outside range may not be the cause of your hair loss. If your hair loss is sudden, patchy or comes with other symptoms, speak to your GP. How to prepare Stop biotin (vitamin B7) supplements for at least 72 hours before collecting your sample. Biotin is common in hair, skin and nail supplements and can affect thyroid results. If you take iron tablets, collect your sample before your daily dose. If you take levothyroxine, collect your sample before your morning dose. Follow the collection instructions in your kit and post your sample the same day, Monday to Thursday. Your results Most samples are analysed the same day they arrive at our laboratory. Every result is reviewed by a UK-registered doctor, and your PDF report is emailed to you, usually within 1–3 working days of your sample arriving. What's included Everything you need to collect your sample at home: lancets, collection tube, request form, alcohol wipes, plasters, full instructions and a prepaid return envelope. Frequently Asked Questions Does this test include vitamin B12? No. This panel measures ferritin, vitamin D, folate, TSH, Free T4 and Free T3. It does not include vitamin B12. Can a blood test tell me why I'm losing hair? It can show whether common factors, such as low iron stores, low vitamin D or a thyroid problem, may be playing a part. Many types of hair loss don't show up in blood tests, so your results should be looked at alongside your symptoms and history. Is my sample sent to another laboratory? No. London Health Company is the laboratory. Your sample is analysed in-house at our own CQC-regulated laboratory in London. Most samples are analysed the same day they arrive, and every result is reviewed by a UK-registered doctor before it is emailed to you.

Stop guessing which foods are causing your symptoms a data-backed map of your digestive health. We are constantly encouraged to eat a well-balanced, diverse diet. But what happens when the healthy foods you eat are secretly triggering negative reactions? Unlike immediate food allergies, a food intolerance is a delayed hypersensitivity reaction mediated by IgG antibodies. Because symptoms can take anywhere from 2 to 72 hours to manifest after eating, it is difficult to pinpoint the culprit using a standard food diary alone. These hidden sensitivities promote chronic, low-grade inflammation, manifesting as persistent bloating, irritable bowel syndrome (IBS), migraines, stubborn skin rashes, joint aches, and constant fatigue.

Parameter tested with this kit Folate (Vitamin B9) Folates are compounds derived from pteroylglutamic acid (PGA) that act as coenzymes in metabolic processes involving the transfer of single-carbon units between molecules. Along with vitamin B12, folate is crucial for DNA synthesis, which is necessary for the proper maturation of red blood cells. Humans obtain folate from dietary sources such as fruits, leafy green vegetables, yeast, and organ meats. It is absorbed in the small intestine and stored in the liver.   Folate deficiency can result from inadequate dietary intake, malabsorption due to gastrointestinal disorders, pregnancy, and certain medications like phenytoin. Chronic alcoholism is also linked to folate deficiency. Both folate and vitamin B12 deficiencies impair DNA synthesis, leading to macrocytic anaemia. This condition is characterized by abnormal red blood cell precursor development in the bone marrow, the presence of megaloblasts, and reduced red blood cell lifespan.   Since macrocytic anaemia can result from either folate or vitamin B12 deficiency, accurate diagnosis is essential for appropriate treatment. Serum folate measurement provides an early indication of folate status.  Frequently Asked Questions What does this test measure? This test measures folate (vitamin B9) in your blood. It is a single-marker test and does not measure vitamin B12, ferritin or vitamin D. Can low folate cause fatigue? Low folate can contribute to anaemia, which may cause tiredness and weakness. Fatigue has many possible causes, so a folate result alone cannot explain every case. Discuss persistent symptoms with your GP. Who is most at risk of folate deficiency? People with a diet low in folate-rich foods, conditions that affect nutrient absorption such as coeliac disease, heavy alcohol use, or certain medications may be at higher risk. Folate requirements also increase during pregnancy. Do not stop prescribed medication without medical advice. How do I collect my sample? Collect a small finger-prick blood sample at home using the kit. Follow the instructions supplied with your kit for collection and returning your sample for laboratory analysis. Does this test check vitamin B12 as well? No. This kit measures folate only. Folate and vitamin B12 deficiencies can cause similar blood changes, so your doctor may recommend further assessment depending on your symptoms and results. Is my sample sent to another laboratory?
