Cobalamins
Measures blood levels of vitamin B12 (cobalamin).
Why This Biomarker Matters
B12 is essential for nerve and blood cell health. Deficiency causes anemia, nerve damage, and cognitive decline. Low levels require supplementation to prevent permanent damage.
Overview
Cobalamin, also known as vitamin B12, is an essential nutrient required for nerve function, red blood cell formation, and DNA synthesis. This test measures B12 levels in blood. Deficiency causes pernicious anemia, nerve damage, and cognitive problems. B12 deficiency is common in vegetarians, older adults, and people with gastrointestinal disorders. Low levels require supplementation through injections or high-dose oral supplements to restore normal function.
