An 18-marker blood test focused on active vitamin B12 alongside folate, iron status and a full blood count, for investigating low energy, mood changes or suspected B12 deficiency.
18 biomarkers as listed by Medichecks.
This test measures active vitamin B12 directly, rather than total B12, alongside folate, ferritin and a full blood count including red cell indices, which can point to anaemia. Low B12 or folate can cause tiredness, low mood and difficulty concentrating, and checking active B12 alongside red blood cell markers gives a clearer picture than a B12 level on its own.
There isn't a matched comparison group for this specific test in our tracking yet, so we can't weigh it against named rivals. It scores well for value because, at £89, it comes in below the typical price for similarly sized vitamin tests we track.
Clinical depth scores highly for an 18-marker panel focused on this area. Trust signals reflect the provider's Trustpilot rating, UKAS ISO 15189 partner labs and included doctor review, and results and follow-up scores well because a doctor reviews the results. Collection convenience is middling, since it needs a clinic visit or a booked nurse visit rather than a home kit.
This suits anyone with symptoms such as fatigue, low mood or concentration problems who wants to check specifically for a B12 or folate deficiency, or who is already managing a known deficiency and wants to monitor it alongside a full blood count. We don't have comparable tests in this group yet, so we can't point you to a cheaper or deeper alternative.
The sample is a venous blood draw, taken in-store at a clinic or via a home nurse visit; there's no at-home finger-prick option for this test. Results are reviewed by a doctor and are typically back within 3 days.
