Checks your blood level of vitamin B6 (pyridoxine), which supports brain function, red blood cell production and protein metabolism. Suited to anyone wanting to check for a deficiency behind low mood or fatigue.
1 biomarker as listed by Medichecks.
Vitamin B6 (pyridoxine) is involved in brain function, the production of red blood cells and how your body processes protein. This test measures only that one marker, so it is a targeted check rather than a broad health screen, useful if you already suspect a B6-specific issue such as tiredness, low mood or nerve symptoms linked to diet or medication.
Against the other single- and few-marker vitamin tests we track, this one scores well on clarity, since Medichecks publishes the biomarker list, sample type, turnaround and collection options in full. It scores less well on value, because £119 is around 40% above the £85 median for similarly sized vitamin tests, and on convenience, since it needs a venous blood draw at a clinic or a home nurse visit rather than a simple finger-prick kit.
The trust and results scores are both strong: every Medichecks test includes a doctor's written comment on your results, and the company uses UKAS ISO 15189 accredited partner labs. If a single-marker check like this is what you need, those factors offset some of the price premium, but it is worth confirming you cannot get the same marker more cheaply as part of a broader panel.
This suits someone who wants to check vitamin B6 specifically, for example when a GP or dietitian has flagged a possible deficiency from diet, alcohol intake or certain medications, and a full nutritional workup is not needed. If your main concern is broader fatigue or low mood with no clear cause, discuss with a GP whether a wider panel of markers would be more useful than testing this one vitamin alone.
This is a blood test. You can have your sample taken at a Medichecks in-store clinic, via a home nurse visit, or as a venous draw at a clinic; it is not available as an at-home finger-prick kit. Once your sample reaches the lab, results are typically ready in around 7 days, and every result comes with a doctor's written comment as standard.
This is a single-marker blood test for vitamin B6, reviewed by a doctor and returned in around 7 days. At £119 it sits well above the £85 median we see across similarly sized vitamin tests, and you will need a venous draw at a clinic rather than a home kit. The biggest catch is the price for what is a narrow, one-marker panel.
