Vitamin B12 Blood Test

Vegans, vegetarians, and anyone over 50 or taking metformin — the groups at highest risk of B12 depletion. Also relevant for people experiencing fatigue, brain fog, or tingling in extremities with no clear cause.

Your serum B12 level against clinical reference ranges, with a clear indication of deficient, borderline, or optimal status. Deficiency develops slowly and symptoms often appear before levels drop below the formal clinical threshold.

B12 deficiency causes irreversible neurological damage if left untreated — but it is entirely preventable once identified. Supplementation is cheap and effective. This test removes all uncertainty in 24 hours.
