About the test

This test measures the level of folate inside red blood cells (RBC) to help diagnose nutritional deficiencies. Since serum folate levels can quickly change with diet and absorption, RBC folate may be a better diagnostic tool since the levels remain fairly constant.

Who might consider it:

This test may be recommended for individuals showing symptoms of folate deficiency or those those being monitored due to specific risks.
