An at-home blood test measuring vitamin B12 levels, useful for vegans, vegetarians and anyone with symptoms of low energy or tiredness that could point to a deficiency.
1 biomarker as listed by Randox Health.
Vitamin B12 supports energy levels, and the provider links low levels to tiredness, weakness, difficulty concentrating, and pins and needles in the hands and feet. Vegans and vegetarians are noted as being at higher risk, since B12 is mainly found in meat, fish, dairy and eggs, along with people with certain gut conditions, pernicious anaemia, or long-term use of stomach acid-reducing medication.
Against the 7 other B12 tests in our comparison data, this one sits exactly at the £46 median, with no premium or discount either way. Medichecks and London Medical Laboratory both offer the same single marker for £39, while Blue Horizon's two B12 tests are £45.25, and Forth, Better2Know and Bluecrest Wellness all charge more, up to Better2Know's £170 Vitamin B12 Test.
The scores reflect a straightforward, fairly priced, convenient test. Value for money sits in the middle since it matches the group median exactly. Collection convenience scores well because it can be done at home, though total time including postage runs a little longer than the stated 2 to 3 day lab window. Clinical depth is treated as a single-marker test doing exactly what it sets out to. Results and follow-up scores lower since results are not reviewed by a doctor as standard.
This suits people who suspect low B12, including vegans, vegetarians, or anyone with a relevant gut condition, and who would rather test at home than visit a clinic. If the lowest price matters most, Medichecks or London Medical Laboratory offer the same single marker for £39, £7 less.
You use the QuickDraw Premium kit at home, which draws blood from the upper arm using the Tasso+ device rather than a finger-prick. You post the sample to the lab, and results are available within 2 to 3 working days of arrival, though they are not reviewed by a doctor as standard.
This at-home test measures vitamin B12 on its own, using a device that draws blood from the upper arm, with results in 2 to 3 working days.
