A blood test covering six B vitamins measured individually: B1, B2, B3, B6, folate and B12. Suited to a detailed look at B vitamin status rather than a quick single-marker check.
6 biomarkers as listed by Blue Horizon Medicals.
This test measures six B vitamins individually rather than as a single combined score: B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), folate (B9) and B12. The provider notes these six cover most of the B group, excluding pantothenic acid and biotin, which are widely available in food and rarely deficient. B12 and folate deficiency are commonly linked to tiredness and, if left unchecked, effects on red blood cells and nerve function; B6 is commonly discussed in relation to nerve function.
This breadth places the panel well above the median marker count for the vitamin tests we track. The trade-off is price: at £255.25 it costs roughly three times the £89.00 median for similarly sized vitamin panels we track, a premium of around 187%.
It scores very well for clinical depth given the number of vitamins covered individually, and well for documentation, since the biomarker list, sample type, turnaround and collection options are all published. It scores very poorly for value for money given that price premium, and modestly for collection convenience, needing a venous draw at a clinic or nurse visit with results back in around 10 days. Results are reviewed by a doctor, and Blue Horizon has traded since 2009 with a Trustpilot score of 4.2 from 395 reviews, using UKAS ISO 15189 partner labs.
This suits someone who specifically wants each B vitamin reported individually rather than as a combined result, and isn't put off by paying well above the typical price for a vitamin panel of this size.
If cost matters more than individual breakdowns, a smaller B12 and folate test, or a general vitamins panel, is likely to be considerably cheaper. If you have symptoms such as ongoing tiredness, talk to your GP rather than relying on self-testing alone.
This is a venous blood test, taken at a Blue Horizon clinic or by a home nurse visit. The sample is tested for B1, B2, B3, B6, folate and B12 individually, with results back in around 10 days. A doctor reviews the results before you receive them.
Six B vitamins, measured individually (B1, B2, B3, B6, folate and B12), for £255.25. That's a detailed panel, well above the typical marker count for vitamin tests we track, but the price is also far above the median, at roughly triple the typical £89.00 cost for similarly sized vitamin tests. Turnaround is around 10 days, with results reviewed by a doctor.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
5 biomarkers, placing it in the 79th percentile of vitamins tests we track.
A blood sample taken at home by a visiting nurse or phlebotomist; with a venous or clinic option as well; a home nurse visit is offered; results in around 10 days, slower than similar tests.
Results are reviewed by a doctor; the provider does not describe the report format.
Trustpilot 4.2 from 395 reviews; accredited lab (UKAS ISO 15189 partner labs); trading 17+ years.
