A folic acid test measures the amount of folate (vitamin B9) in your blood. It is usually ordered to check for a deficiency that can cause anemia or other symptoms, or to monitor folate levels during pregnancy or with certain medications.

What it measures

  • Serum folate — The amount of folate circulating in your blood right now.
  • Red blood cell folate — A longer-term view of folate stored in red blood cells over the past few months.
  • Hemoglobin — Often checked alongside folate to look for signs of anemia.
  • Vitamin B12 — Measured together because low B12 can cause similar symptoms and blood changes.

Who it is for

A clinician may order this test if you have symptoms of anemia, a poor diet, trouble absorbing nutrients, or if you are pregnant or planning pregnancy. It is also used to monitor people taking certain medicines that affect folate.

Preparation

No fasting is usually required. Tell your clinician about all medicines and supplements you take, since some can affect the result.

Results and what they mean

Results are reported as a number with a reference range, and a clinician interprets them alongside your symptoms and other tests. A low or high result does not by itself diagnose a condition. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
