A 20-marker blood panel checking for pernicious anaemia, combining intrinsic factor antibodies, iron and B12 status with a full blood count. Suits people already diagnosed with a B12 deficiency.
20 biomarkers as listed by Medichecks.
This panel covers 20 markers including intrinsic factor antibodies, full blood count markers, ferritin, folate, active vitamin B12 and methylmalonic acid. These markers are commonly used together to help assess whether a vitamin B12 deficiency has an autoimmune cause, alongside the general blood-count picture.
We do not have a comparison group of similar tests to benchmark this one against directly, so it is considered here on its own facts rather than against named peers.
Clinical depth scores at the top of the range because 20 markers puts it in the 95th percentile of the vitamins tests we track, and clarity also scores well because the full biomarker list, sample type and collection options are published. Value for money scores low, since £280 is well above the £119 median for the 13 similarly sized vitamins tests we track, and collection convenience is held back by the venous draw and a turnaround of around 17 days, longer than most other Medichecks tests in this data.
This suits people who have already been diagnosed with a vitamin B12 deficiency and want to check whether an autoimmune cause, such as pernicious anaemia, is contributing, alongside a wider blood-count picture. It is not designed as a first-line or quick check, given the 17-day turnaround.
We do not track a comparable 20-marker pernicious anaemia test from another provider to suggest as a faster or cheaper alternative.
You provide a venous blood sample at an in-store clinic or via a home nurse visit. Medichecks states results take around 17 days, which is longer than most other tests in our data, and every result includes a doctor's comment.
This 20-marker panel checks for pernicious anaemia and vitamin B12 deficiency, covering blood counts, iron status, folate, B12 and intrinsic factor antibodies for £280. It has a notably long turnaround of around 17 days, and every result is reviewed by a doctor; we do not track a directly comparable test to weigh the price against.
The listing publishes a short description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
