Description

This document addresses the use of red blood cell (RBC) folic acid laboratory testing, also known as RBC folate. RBC folic acid measures the level of vitamin B₉, folate. RBC folic acid no longer meets the standard of care in evaluating an individual’s folate levels because serum folate is a more accurate and reliable measurement of folate levels.

Clinical Indications

Not Medically Necessary:

RBC folic acid testing is considered not medically necessary in all cases.
