Vitamin B12 (Active)
The Vitamin B12 (Active) test measures the biologically active form of vitamin B12 (holotranscobalamin) in your blood. Unlike total B12 tests, this one reflects the amount of B12 available for immediate use by your body. It is a more sensitive and early indicator of B12 deficiency, particularly valuable when symptoms are present but total B12 levels appear normal.
