Clinical Significance
Vitamin B12:
This assay is used for quantitative determination of Vitamin B12 in human serum and plasma. Vitamin B12 (B12) is a cofactor for the conversion of methylmalonyl Coenzyme-A (CoA) to succinoyl CoA and also serves as a cofactor in the synthesis of methionine from Homocysteine. B12 is implicated in the formation of myelin, and, along with folate, is required for DNA synthesis.

This assay is used for quantitative determination of folates in human serum and plasma. Folate measurements are used in the diagnosis and treatment of megaloblastic anemia.
