A three-marker blood test covering folate, vitamin B12 and vitamin D together, for a broader nutritional check than a single-vitamin test.
3 biomarkers as listed by London Medical Laboratory.
Folate and vitamin B12 both support healthy blood and nervous system function, and deficiency in either can cause similar symptoms, which is why they are often checked together. Vitamin D is included alongside them, relevant given how common low vitamin D is in the UK, particularly over winter.
At three biomarkers this matches its comparison group's median exactly, while the £89 price is about 8% above the group's £82.45 median. Medichecks checks the same three markers for £74, and Thriva's equivalent vitamins test costs £81.90.
Clinical depth scores well given the marker count matches the group median, while value for money is middling because of the premium over the cheapest peer. Collection convenience is high because the test can be done at home, and trust signals reflect the provider's CQC registration and doctor-reviewed report as standard.
This suits anyone who wants folate, B12 and vitamin D checked together in one sample rather than buying separate single-marker tests. If price is the deciding factor, Medichecks' equivalent three-marker test costs £15 less.
This is a blood test. You can use an at-home finger-prick kit (£3.99 postage), attend a partner clinic for a venous draw (£35), or arrange a phlebotomist home visit. Results are typically ready within a day and are reviewed by a doctor.
This £89 panel checks folate, B12 and vitamin D together, about 8% above the £82.45 median for its comparison group. Medichecks offers the same three markers for £74, so this isn't the cheapest way to check all three, but it can be done with an at-home finger-prick kit.
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.
3 biomarkers against a median of 3 across the 4 tests in its comparison group.
A finger-prick sample you take at home; with a venous or clinic option as well; results in around 1 days, well ahead of the vitamins norm of 3.5.
Results are reviewed by a doctor; the provider does not describe the report format.
No Trustpilot rating on record; CQC registered; doctor review as standard.

Matches the group median on both depth and price
A three-marker blood test measuring active vitamin B12, folate and vitamin D, for checking common nutrient deficiencies linked to energy, mood and immune health.
Cheapest 3-marker B12, folate and ferritin test here
This test measures active B12, folate and ferritin together, three markers linked to energy, red blood cell production and possible anaemia. It suits people with fatigue, dizziness or a suspected deficiency who want a broader check than a single marker.
Pricier and narrower than Medichecks' own 3-marker test
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.
