A focused at-home vitamin deficiency blood test — Vitamin D, total and active B12, and folate: the nutrients most often found low in UK adults. UKAS-accredited UK lab. From £85.
Vitamin D, B12 and folate are commonly low in UK adults, particularly through the winter months. Low levels are associated with fatigue, poor recovery and low mood, and can be present without obvious signs. Testing rather than guessing gives you the numbers — then discuss what they mean, and whether supplementation is appropriate, with your GP or a registered nutrition professional.
We give you access to your data — not medical advice. This test returns laboratory results and general information only. It is not a diagnosis, a treatment or a clinical opinion. No clinician reviews or comments on your results before they reach you — you receive your numbers against standard reference ranges, and interpreting them is for you and your GP. If a result falls outside the reference range, or you feel unwell, contact your GP; in an emergency call 111 or 999. You must be 18 or over to order.
This panel measures 4 biomarkers across 1 area, analysed in a UKAS-accredited UK laboratory. Every marker is listed in full below.
Anyone feeling flat, run-down or recovering poorly, plus vegetarians and vegans (at higher risk of low B12) and anyone through a UK winter. It’s the natural companion to a supplement routine — see our blood-test-to-supplement guide for how to turn results into action.
Finger-prick samples are occasionally rejected by the laboratory because there is too little blood or the sample is too old to test, which means starting again. Four things make that far less likely: collect in the morning, warm your hands first (run them under warm water and let them hang down for a minute), drink plenty of water beforehand, and post the sample back the same day you take it — never on a Friday or Saturday, so it does not sit in the postal system over a weekend.
Who should not use a home kit: if you take anticoagulants, have a bleeding or clotting disorder, or feel faint at the sight of blood, speak to your GP before testing and consider a clinic-collected panel instead. If bleeding does not stop after firm pressure, seek medical advice.
Measuring both total and active B12 gives a truer read on what your body can actually use. This test is for information, not diagnosis — persistent or significant deficiencies should be discussed with your GP. Test, don’t guess, then correct from data. Your results are private. They are handled as confidential health data and delivered to you securely. They are shared only with our laboratory partner in order to process your test, and otherwise never without your consent.
Vitamin D is the most common, especially between October and March when sunlight is limited. B12 and folate are also frequently low, particularly in plant-based diets.
Total B12 measures all B12 in your blood; active B12 measures the portion available to your cells. Active B12 can reveal a developing shortfall that total B12 alone might miss.
For a true baseline, discuss timing with your GP; high-dose B-vitamin or biotin supplements can affect some readings. Otherwise, test to confirm your current routine is working.
Usuallysent as soon as the laboratory reports them of the lab receiving your sample.
Yes — analysed in a UKAS-accredited UK laboratory to clinic standard.
