Check your iron stores with an at-home finger-prick blood test. Ferritin is the protein that stores iron in your body, and measuring it is the standard way to assess your iron stores. Collect your sample at home and post it in the prepaid envelope to our own CQC-regulated laboratory in London.
Your report shows your measured ferritin level 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.
Why do people check their ferritin?
People commonly check their ferritin if they have symptoms such as tiredness, hair thinning or brittle nails, have heavy periods, follow a vegetarian or vegan diet, or want to monitor iron supplements. These symptoms have many possible causes, so speak with a healthcare professional if they persist.
What is tested?
Serum ferritin, a measure of your body's iron stores.
Need a broader test?
Choose an upgrade above, or compare our Iron Status Profile (ferritin plus iron markers), our Nutrients Blood Test (ferritin, vitamin D and folate) or our Fatigue & Tiredness panel. Tiredness can also be linked to thyroid function, so some people add our Thyroid Function test.
Frequently asked questions
What is a ferritin blood test?
A ferritin blood test measures the amount of ferritin in your blood. Because ferritin stores iron, your level gives an indication of how much iron your body has in reserve.
What is a normal ferritin level?
Reference ranges vary between laboratories and differ for men and women. Your report shows your result against our laboratory's reference range. Ferritin can also rise temporarily during infection or inflammation, so share your report with your GP if your result is outside the range or your symptoms continue.
How should I prepare for the test?
Follow the instructions supplied with your kit. See our guide to preparing for your iron profile and ferritin blood test.
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.
How quickly will I get my results?
Most samples are analysed the same day they reach our laboratory. Your report is emailed to you as a secure PDF.

Oestradiol: the main form of oestrogen, also present in men.
Prolactin: a pituitary hormone involved in regulating reproductive hormones.
LH (luteinising hormone): a pituitary hormone that signals the testes to produce testosterone.
FSH (follicle-stimulating hormone): a pituitary hormone involved in sperm production.
Who is this test for?
Men commonly choose this panel if they want a broader picture than testosterone alone, for example if they are experiencing tiredness, low libido or low mood, or if they are monitoring testosterone replacement therapy (TRT) with their prescriber. These symptoms have many possible causes, so speak with a healthcare professional if they persist.
Looking for something different? Compare our Total Testosterone test, our 4-marker Male Hormone Panel, or our TRT blood work panel, which adds cholesterol, liver and kidney markers.
How to collect your sample

Frequently asked questions
Why is the test taken in the morning?
Testosterone levels are usually highest in the morning and fall during the day. Reference ranges are based on morning samples, so collecting before 10:00 am makes your result easier to interpret.
Do I need to fast?
Follow the preparation instructions supplied with your kit and in our preparation guide.
Why are prolactin, LH and FSH included?
These pituitary hormones help put a testosterone result into context, because they are involved in regulating testosterone production. Your doctor can interpret them alongside your symptoms and history.
Can I use this test if I am on TRT?
Yes. Follow your prescriber's advice on when to collect your sample relative to your treatment. Do not change or stop TRT based on this test without speaking to your prescriber. For a fuller monitoring panel, see our TRT blood work panel.
Is a finger-prick sample suitable?
Yes. Your finger-prick sample is analysed in our laboratory on professional laboratory analysers. Following the collection instructions carefully, including filling the tube to the line, is the most important step for a reliable 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. 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.

It is not sent to a third-party lab.Does this replace medical care?No. This is a private laboratory testing service, not a replacement for medical assessment or ongoing diabetes care. If you have new or worsening symptoms or feel unwell, seek medical advice rather than waiting for a home test or its results.
Frequently Asked Questions
What do HbA1c results mean?
HbA1c is reported in mmol/mol. NHS guidance generally uses these ranges for adults: below 42 mmol/mol is in the normal range, 42–47 mmol/mol may indicate a higher risk of type 2 diabetes (sometimes called prediabetes), and 48 mmol/mol or above can indicate diabetes. Only a doctor can diagnose diabetes, usually with a repeat test. Share your report with your GP if your result is 42 mmol/mol or above.
Do I need to fast before an HbA1c test?
No. HbA1c reflects your average blood sugar over the past two to three months, so you do not need to fast and can collect your sample at any time of day.
How often should I test my HbA1c?
This depends on your circumstances and what your healthcare professional advises. Read our guide on how often to test HbA1c.
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.

Understanding your resultsYour report can support a conversation with your GP or another qualified healthcare professional. A result outside the laboratory reference range does not establish a diagnosis on its own, and results within range do not rule out every health condition.If you have symptoms or concerns, seek medical advice rather than relying on this test alone. Do not stop or change prescribed treatment based on your results without advice from your prescriber.
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 vitamin D level with an at-home finger-prick blood test. Collect a small sample at home and return it using the included prepaid envelope for analysis at our own CQC-regulated laboratory in London.
Your report shows your measured 25-hydroxyvitamin D (25-OH vitamin D) level alongside laboratory reference ranges. Most samples are analysed the same day they reach our laboratory, and every result is reviewed by a UK-registered doctor before it is sent to you.
What does this test measure?
This test measures 25-OH vitamin D, the form of vitamin D in your blood that is most widely used to assess vitamin D status. It reflects vitamin D from sunlight, food and supplements.
Why do people check their vitamin D in the UK?
Your skin makes vitamin D from sunlight. In the UK, sunlight between October and early March is not strong enough for most people to make enough, which is why the NHS advises that everyone considers a daily vitamin D supplement during autumn and winter.
People commonly check their level if they:
spend little time outdoors, or usually cover most of their skin when outside
have darker skin, which makes less vitamin D from the same amount of sunlight
take a vitamin D supplement and want to see their current level
want a baseline measurement before or after the winter months
Is this test right for you?
This test measures your vitamin D level. If you are investigating symptoms such as tiredness, aches or low mood, speak with a healthcare professional. These symptoms have many possible causes, and a vitamin D result alone cannot explain them.
What is included?
Finger-prick lancets and a blood collection tube
Laboratory request form and collection instructions
A prepaid return envelope
Laboratory analysis of 25-OH vitamin D
A numerical report with reference ranges, reviewed by a UK-registered doctor
How it works
Order your kit and read the enclosed instructions.
Collect your finger-prick sample. No fasting is needed and you can test at any time of day.
Return your sample using the prepaid envelope.
Receive your report. Most samples are analysed the same day they reach our laboratory.
Frequently asked questions
What is a normal vitamin D level?
In the UK, a 25-OH vitamin D level below 25 nmol/L is generally considered deficient, and a level above 50 nmol/L is generally considered sufficient for most people. Your report shows your result against our laboratory's reference ranges. If your result is outside the range, share your report with your GP or another qualified healthcare professional.
Do I need to fast before a vitamin D test?
No. Fasting is not needed, and you can collect your sample at any time of day. Drinking water beforehand and keeping your hands warm can make finger-prick collection easier.
Should I stop taking vitamin D supplements before the test?
Follow the instructions supplied with your kit. If you are testing to see whether your current supplement is working, note the dose you take on your request form. Do not stop or change any prescribed vitamin D without advice from your prescriber.
When is the best time of year to test?
Vitamin D levels are usually lowest in late winter and early spring, and highest in late summer. Testing at the same time of year helps you compare results over time.
How quickly will I get my results?
Most samples are analysed the same day they reach our laboratory. Every result is reviewed by a UK-registered doctor before it is sent to you.
Does this replace seeing my GP?
No. This is a private laboratory test, not a diagnosis or treatment plan. If you feel unwell or are worried about your health, speak to your GP or NHS 111.
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 iron levels and blood health with our private Iron, Ferritin and Blood Count Test Kit, collected at home with a simple finger-prick and analysed in our own CQC-regulated London laboratory. If you've been feeling tired, run down or noticed changes in your hair, this test gives you a clear picture of both your iron stores and your red and white blood cells, with every result reviewed by a UK-registered doctor.
It's a popular choice for people who feel "Tired All The Time" (TATT), active people who want to understand their recovery, and vegans and vegetarians keeping an eye on their iron intake. Testing gives you a reliable baseline, shows whether your iron and blood count sit within the normal range, and lets you track changes over time. If your results suggest low iron, anaemia or high iron levels, we'll recommend you share them with your GP.
Who Should Take This Test?
People with Low Energy: If you're dealing with ongoing tiredness, weakness, brain fog or unexplained aches, low iron is one of the common things worth checking.
Vegans & Vegetarians: Iron from plant foods is less easily absorbed, so it's worth checking your levels from time to time.
Athletes & Active People: Iron is needed to make haemoglobin, which carries oxygen around the body, so regular training can make it worth keeping an eye on your levels.
Women's Health: Heavy periods and pregnancy can both lower iron stores over time.
How to Prepare & Take Your At-Home Test
Test in the Morning: Iron levels naturally change throughout the day, so collect your sample before 10am for the most consistent result.
Stay Well Hydrated: Drink plenty of water beforehand to help your blood flow and make collecting your finger-prick sample easier.
Post Your Sample the Same Day: Return your sample to our lab in the prepaid envelope as soon as you've collected it.
Common Symptoms of Low Iron & Anaemia
Low iron can develop gradually without obvious early signs, but common symptoms include:
Ongoing tiredness, lack of energy or weakness
Pale skin, or cold hands and feet
Feeling short of breath during everyday activities or exercise
Frequent headaches or difficulty concentrating
Brittle nails, thinning hair or hair loss
These symptoms can have many causes. If they persist, or you're concerned, please speak to your GP.
Frequently Asked Questions
What is the difference between iron and ferritin?
Serum iron is the amount of iron circulating in your blood at the time of your test, and it can change from hour to hour. Ferritin reflects how much iron your body has in storage. Ferritin usually falls before other markers change, which makes it a useful early indicator of low iron stores.
Why should I collect my sample in the morning?
Iron levels follow a daily rhythm and are usually highest in the morning. Collecting your sample before 10am gives the most consistent result and makes it easier to compare if you test again.
What does the full blood count show?
A full blood count looks at your red blood cells, white blood cells and platelets, including haemoglobin, the protein that carries oxygen around your body. Alongside your iron results, it helps show whether low iron is affecting your red blood cells.
How quickly will I receive my lab results?
Once your sample reaches our CQC-regulated London laboratory, it will be analysed and reviewed by a doctor. Your confidential results will be uploaded to your secure dashboard and emailed to you within 1–2 working days.
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.
Track the key nutrients that drive your energy, weight loss, and mood.
Nutrients are the essential building blocks your body relies on every single day. They fuel your cells, support organ function, and help regulate everything from your metabolism to your mental clarity. When your nutrient levels fall out of balance, it quickly reflects in your daily life through unexplained fatigue, poor concentration, hair shedding, stubborn weight struggles, and even brittle nails or dry skin.
Our Comprehensive Nutrients Blood Test Kit is designed to measure your active Folate, Ferritin (iron storage) and Vitamin D levels. By checking these three markers in one single at-home screen, you can accurately pinpoint hidden deficiencies and take immediate action to optimize your health.
Why These Core Nutrients Matter
Energy & Mental Clarity: Iron, and folate are completely essential for helping your body produce red blood cells and deliver oxygen to your brain and muscles. Optimizing these levels directly impacts how energized, focused, and sharp you feel throughout the day.
Weight Management & Metabolism: Low levels of Vitamin D can actively slow down your metabolism, making it significantly harder to lose weight or maintain a healthy body composition.
Hair, Skin & Nail Health: Nutrient deficiencies are one of the most common biological causes of hair thinning, brittle nails, and dull skin. Ferritin and folate are particularly important for encouraging healthy cellular growth and renewal.
Immune Strength & Mood Balance: Vitamin D is proven to help regulate your mood, reduce brain fog, and keep your immune system in fighting shape, especially during the darker UK winter months.

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.
This iron blood test checks five markers from one finger-prick sample you collect at home, giving a fuller picture than ferritin alone. It's analysed in our own CQC-regulated laboratory in London, and every result is reviewed by a UK-registered doctor.
Biomarkers included
Ferritin: your iron stores. Usually the first marker to fall when iron runs low.
Serum iron: the iron circulating in your blood. It varies through the day, so it's read alongside the other markers.
Transferrin: the protein that carries iron in the blood
TIBC (total iron-binding capacity): how much iron your blood could carry
Transferrin saturation: how "full" transferrin is with iron, shown as a percentage
Who this test is for
People with tiredness, low energy or hair shedding who want to check their iron
People with heavy periods, who are vegetarian or vegan, or who give blood regularly
People taking iron tablets who want to check their levels
People who have been told their ferritin is high and want the wider iron picture
Tiredness has many causes, and an iron test can't explain every one. If you're tired all the time, our Fatigue & Tiredness Blood Test adds a full blood count to check for anaemia. Speak to your GP if you're short of breath, have palpitations or have lost weight without trying.
How to prepare
Collect your sample in the morning, before breakfast if you can, because serum iron changes through the day.
If you take iron tablets, collect your sample before your daily dose, ideally 24 hours after the last one.
Don't test while you're unwell, because infection and inflammation raise ferritin.
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
What's the difference between an iron test and a ferritin test?
A ferritin test measures your iron stores only. This iron profile adds serum iron, transferrin, TIBC and transferrin saturation, which helps show whether a ferritin result reflects low iron, too much iron or inflammation.
Can I test my iron levels at home?
Yes. You collect a small finger-prick sample at home and post it to our laboratory in the prepaid envelope. We analyse it and email you a doctor-reviewed report.
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.
Low or imbalanced electrolyte levels can affect muscle function, nerve signalling, bone health, and energy. This home blood test measures calcium and magnesium, two essential electrolytes that are frequently overlooked in standard blood panels, giving you clear, quantitative results from a CQC-regulated UK laboratory.
An electrolyte blood test is used to measure the levels of electrolytes in a person's blood. Electrolytes carry an electric charge and play a vital role in maintaining proper fluid balance, nerve function, muscle contraction, and other important bodily functions.
This test gives you the levels of Calcium and Magnesium in your blood.
This electrolytes home blood collection kit contains everything you need to collect blood and send it to our laboratory for analysis. Inside, you'll find lancets, instructions, lab request form, labels, tube, tube pouch, prepaid UN3373 envelope, tube holder, swabs, alcohol wipes, and plasters. No need to go to the post office; simply drop off your sample in the nearest red letterbox.
The report will be quantitative, containing actual figures and remarks for results that fall outside the normal range. The report will be sent to your email.
The Role of Electrolytes in Blood
1. **Maintaining Fluid Balance:** Electrolytes play a significant role in regulating the balance of fluids inside and outside cells. Sodium and potassium, in particular, help control the movement of water in and out of cells, maintaining proper hydration levels.2. **Nerve Signalling:** The transmission of nerve signals relies heavily on the movement of ions, which are charged particles produced by electrolytes. Sodium and potassium ions, for instance, contribute to generating and transmitting electrical impulses that allow muscles to contract and nerves to communicate.3. **Muscle Contraction:** Calcium is a crucial player in muscle contraction. It helps muscles contract and relax in response to nerve signals. Magnesium also plays a role in muscle function and helps prevent excessive muscle contractions.4. **pH Balance:** Electrolytes help regulate the pH balance of your blood, ensuring that it remains within a narrow range. Maintaining the right pH is vital for various biochemical reactions and enzymatic processes.

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.
Can I test for magnesium deficiency at home?
Yes. You collect a small finger-prick blood sample at home and post it to our lab, where we measure the magnesium in your serum. A serum test shows the magnesium circulating in your blood rather than the total stored in your body, so your result is best looked at alongside any symptoms with your GP.

Frequently Asked Questions
Do I need to fast before taking a Blood Count test?
No, fasting is not required for a standard Blood Count test. You can collect your sample at any time of day, though staying well-hydrated beforehand makes finger-prick collection easier.
Can this blood test detect iron deficiency anaemia?
Yes. By measuring your Haemoglobin (Hb), Red Blood Cell Count (RBC), and Hematocrit (HCT), this panel helps identify low levels associated with iron deficiency anaemia and oxygen transport issues.
Is finger-prick sample collection as accurate as a clinic blood draw?
Yes. Once your blood sample arrives at our CQC-regulated UK laboratory, it is processed on the exact same clinical diagnostic machinery used for hospital venous blood draws.
How quickly will I receive my results?
Your quantitative laboratory report will be reviewed by a qualified doctor and emailed to you within 1 to 3 working days of reaching our lab.
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 cholesterol levels at home with a finger-prick blood sample, then post it to our own CQC-regulated London laboratory using the prepaid return envelope. Your lipid profile report includes total cholesterol, HDL, LDL, triglycerides, non-HDL cholesterol and your cholesterol:HDL ratio. Most samples are analysed the same day they reach our lab, and every result is reviewed by a UK-registered doctor.
This is a home sample-collection kit with laboratory analysis, not an instant cholesterol meter or test strip.
Skip the clinic and get a quantitative lab report showing your Total Cholesterol, HDL Cholesterol, LDL Cholesterol and Triglycerides, together with your Non-HDL Cholesterol and Cholesterol:HDL Ratio. Most samples are analysed the same day they reach our lab, and your results are then sent securely to your email. The report is fully quantitative, showing your actual figures and reference ranges, with clear remarks on any results outside the normal range. Every result is reviewed by a UK-registered doctor before it is sent to you.
Why Your Report Includes Cholesterol Ratios
Total cholesterol on its own doesn't tell the whole story. Two people can have the same total cholesterol but a very different balance between protective and less favourable cholesterol underneath it. That's why your report now includes two extra results, calculated from your sample at no extra cost.
Your Cholesterol:HDL Ratio shows how much of your cholesterol is the protective HDL kind. It is one of the values GPs use to calculate a QRISK score, which estimates the chance of a heart attack or stroke over the next ten years. A lower ratio is generally considered more favourable.
Your Non-HDL Cholesterol is your total cholesterol minus your HDL. It brings together LDL and other lipoproteins that can contribute to build-up in the arteries, giving a broader view than LDL alone. NICE guidance uses non-HDL cholesterol when monitoring statin treatment, which makes it especially useful for cholesterol monitoring while on statins.
Who Should Test Their Cholesterol & Lipid Profile?
This test is suitable for adults who want a clearer understanding of their cholesterol levels, including those with a family history of heart disease, those interested in cholesterol monitoring while on statins, or anyone seeking objective data as part of a proactive approach to long-term heart health.

Frequently Asked Questions
Do I need to fast before a lipid profile blood test?
We recommend fasting for 10 to 12 hours (water only) before taking your sample. Triglycerides rise after eating, and LDL is calculated partly from your triglyceride level, so a fasted sample gives the most reliable and comparable results. If you are unable to fast, please note this on your lab request form so your results can be interpreted in the right context.
Can I take this test if I am on statins?
Yes. This panel includes non-HDL cholesterol, the marker NICE uses to monitor statin treatment, so it is well suited to cholesterol monitoring while on statins and checking how your lipid levels change over time.
What is the difference between HDL and LDL cholesterol?
HDL Cholesterol carries excess cholesterol away from your arteries to the liver for removal, while LDL cholesterol can build up along artery walls when levels are high.
What do my Cholesterol:HDL Ratio and Non-HDL results tell me?
They show the balance between protective and less favourable cholesterol in your blood. A lower ratio and a lower non-HDL level are generally considered more favourable. If either result falls outside the reference range, we recommend sharing your report with your GP, who can consider it alongside your wider health.
Do I need to do anything extra to get my ratio and non-HDL results?
No. Both are calculated from the markers we already measure in your sample, so there is no extra blood needed and no extra cost.
How quickly will I receive my cholesterol test results?
Most samples are analysed the same day they arrive at our CQC-regulated London laboratory. Every result is reviewed by a UK-registered doctor before it is emailed to you.
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.
