WebThis preview shows page 2 - 3 out of 16 pages. Folate is the second most important vitamin for erythrocyte production and maturation. Folate is necessary for DNA synthesis, being a component of three of the four DNA bases (thymine, adenine, and guanine), and RNA synthesis. 1. Vitamin C is needed for proper iron metabolism. WebA B12 level < 200 pg/mL (< 147.6 pmol/L) or folate level < 2 ng/mL (< 4.53 nmol/L) is generally diagnostic of deficiency. B12 levels between 200 to 300 pg/mL (147.6 to 221.3 pmol/L) are nondiagnostic. When vitamin B12 levels are not diagnostic, both a methylmalonic acid (MMA) and homocysteine (HCY) level should be checked.
