Brain Fog

Your thyroid is a small, butterfly-shaped gland that acts as the master control center for your entire metabolism. It produces vital hormones that dictate exactly how your body uses energy, regulates temperature, manages weight, and maintains your mood. When your thyroid is sluggish (hypothyroidism) or overactive (hyperthyroidism), it can manifest as unexplained weight gain or loss, persistent exhaustion, constant feeling of cold or heat, thinning hair, and brain fog. Standard medical checks often only screen for TSH (Thyroid Stimulating Hormone), which frequently misses the full clinical picture. Our laboratory Thyroid Function Blood Test  delivers a comprehensive overview of your hormonal health by measuring the three most critical thyroid markers simultaneously: TSH, Free T3 (FT3), and Free T4 (FT4). By looking at both the stimulating hormone and the active thyroid hormones circulating in your blood, this profile lets you see exactly how well your thyroid gland is performing. How to complete your thyroid test from home: Monitoring your metabolic health is completely private and straightforward. There is no need to queue at a clinical center or wait weeks for an appointment slot.

Are you experiencing persistent fatigue, low energy, shortness of breath, or noticeable hair loss? Low ferritin, the protein that stores iron in your body, is one of the most common and overlooked causes. This simple home blood test measures your exact iron storage levels, helping you identify iron deficiency before it progresses to anaemia. Ferritin deficiency is commonly linked to: Chronic fatigue or low energy Hair thinning or hair loss Brittle nails or pale skin Weakness or difficulty concentrating Early detection allows for targeted action, whether that's dietary changes, iron supplementation, or further medical evaluation. What is tested: Serum Ferritin — a sensitive marker of your body's available iron stores and the most reliable indicator of iron-deficiency anaemia. Also worth considering: While ferritin checks your iron storage, unexplained fatigue is also frequently caused by thyroid imbalances. If you want a complete picture in one sample, consider adding our Thyroid Profile (TSH, Free T3 and Free T4) to your order. Your results: Delivered as a secure PDF report to your email within 3 working days of your sample arriving at our laboratory. Results are quantitative, showing your exact ferritin level alongside reference ranges and notes for any values outside the normal range. All samples are processed in a CQC-regulated UK laboratory.

Vitamin B12 is an essential nutrient that your body relies on to function properly, yet it cannot produce it on its own. It plays an indispensable role in red blood cell formation, neurological function, DNA synthesis, and cellular energy production. When your B12 levels run low, it can show up in your day-to-day life as unrelenting fatigue, constant muscle weakness, annoying pins and needles, mood swings, and frustrating brain fog. Our At-Home Vitamin B12 Blood Test Kit is a clinical-grade check designed to measure your exact levels of active B12 circulating in your blood. Unlike generic diet diaries or symptom tracking, this simple blood test gives you an undeniable biological snapshot of your internal health. It is an absolutely vital check for vegans, vegetarians, and plant-based eaters, as Vitamin B12 is almost exclusively found in animal-derived foods. It is also highly recommended for older adults or anyone taking long-term acid reflux medications, which can drastically inhibit dietary B12 absorption. How to test your B12 levels from home: There is no need to book a clinic slot or wait for a standard doctor's appointment. Our kit includes everything required to complete the test completely from the comfort of your living room. Simply perform a quick, minimally invasive finger-prick using the provided sterile lancet to collect a small blood sample into the collection tube. Once done, place your sample into the prepaid return envelope and drop it into any priority postbox. Your sample is routed directly to our CQC-regulated UK laboratory for expert analysis, guaranteeing hospital-grade accuracy and strict data privacy. Within 1 to 3 working days of laboratory receipt, your final quantitative results will be securely delivered to your private digital dashboard, complete with clear visual reference ranges and professional doctor-reviewed commentary.
