This test measures active vitamin B12 and folate, two nutrients involved in energy, brain function and red blood cell production. It suits people who want to check both markers together, such as vegans, vegetarians or those with absorption issues.
2 biomarkers as listed by Medichecks.
Active vitamin B12 and folate both support energy levels, brain function and the production of red blood cells, and testing them together is a common way to check for a deficiency if you are vegan, vegetarian, or have a condition that affects nutrient absorption.
This test measures two markers, slightly below the median of four biomarkers seen across similar vitamin B12 and folate tests we track. On price it sits close to the middle of that group at £83, but it is worth noting that Medichecks' own Vitamin B12 (Active) Folate and Ferritin Blood Test costs less, at £74, while adding a third marker (ferritin); Thriva's three-marker vitamins test is priced similarly to this one at £81.90.
Collection requires a venous blood draw at a clinic or via a home nurse visit rather than an at-home finger-prick, which holds back the collection convenience score, while trust signals remain strong on the back of the provider's Trustpilot record, lab accreditation and trading history, and every result is reviewed by a doctor.
This suits you if you specifically want active B12 and folate checked together and do not need ferritin as well. If you are comfortable adding a third marker, Medichecks' own Vitamin B12 (Active) Folate and Ferritin Blood Test costs less at £74 and covers iron status too, which makes it the better value choice from the same provider.
If you would rather avoid a clinic visit altogether, this is not the test for you, since it requires a venous draw rather than a finger-prick sample.
The sample is taken as a venous blood draw at an in-store clinic or through a home nurse visit; there is no at-home finger-prick option for this test. The lab tests for active vitamin B12 and folate, a doctor reviews your results, and your report is typically ready in around 4 days.
At £83, this two-marker vitamin B12 and folate test costs more than Medichecks' own three-marker Vitamin B12 (Active) Folate and Ferritin test at £74, and sits close to Thriva's £81.90 three-marker vitamins test. Collection needs a venous draw at a clinic or home nurse visit, with results back in around 4 days and a doctor's comment included.
