Boost Immunity with Vitamin C Test

A vitamin C (ascorbic acid) test measures the level of this water-soluble vitamin in plasma or blood serum. Vitamin C acts as an essential cofactor in the synthesis of collagen, carnitine, and certain neurotransmitters. It is a powerful antioxidant that protects cells from damage caused by free radicals, enhances the absorption of non-heme iron, and supports immune function.
