FOLATE – RBC

Folate testing of the red blood cells (RBC) is a common way to determine if a person doesn’t get enough folic acid. If your red blood cell folate levels are low, it may indicate that you aren’t getting enough folic acid, that you don’t absorb it very well, or that you need more.

RBC folate testing may also be helpful for individuals with a liver illness or who use drugs that make it difficult to absorb folate since these situations are the same as those with liver disease.
