A finger-prick home blood test that checks your folate (vitamin B9) level, useful for tracking deficiency risk without visiting a clinic.
1 biomarker as listed by Better2Know.
This test measures folate, also called vitamin B9, a nutrient involved in making red blood cells and, particularly for anyone who could become pregnant, in protecting a developing baby's neural tube. Low folate can also allow homocysteine to build up, which the provider links to cardiovascular risk.
There is no named comparison group for this specific kit, but against the 73 similarly sized vitamin tests we track, its £99 price sits close to the £85 median, and a single folate marker places it in the lower-middle range for clinical depth among that wider set. Better2Know also sells a clinic version of this test for £185, so the home kit is the cheaper of the provider's own two options.
It scores well for collection convenience, since you can do the whole thing from home with a finger-prick sample and results within a day or two, and for clarity, given the sample type, collection route and turnaround are all clearly stated. It loses marks on results and follow-up because the result is not reviewed by a doctor as standard.
This suits someone who wants a low-effort way to check their folate level at home, including people managing their diet or a possible deficiency, without needing a nurse visit.
If you would rather have blood drawn by a professional, Better2Know's own clinic version of this test is available for £185, though that is a considerably higher price for the same single marker. Speak to a GP directly if you are pregnant or planning a pregnancy and are concerned about your folate levels.
You take a finger-prick blood sample at home using the kit provided and post it to the lab; Better2Know also offers a venous-draw clinic version of this test for £185 if you would prefer that instead. Once the sample arrives, it is processed for a single folate (vitamin B9 serum) marker, with results typically available within about a day, accessible through Better2Know's online patient area. The provider does not state that results are reviewed by a doctor as standard.
Better2Know's Vitamin B9 Serum Home Test Kit costs £99 and measures a single folate marker from a finger-prick sample you take yourself. That sits close to the £85 median we see across similarly sized vitamin tests, so it is neither a bargain nor overpriced for a single-marker home kit. The main gap is that Better2Know does not review the result with a doctor as standard.
