What is this test?
Folic acid (vitamin B9) is essential for cell renewal and blood cell production. Deficiency can cause anemia; folate is also important for fetal development before and during pregnancy. It is usually ordered together with vitamin B12.
When is it requested?
Diagnosis of folate deficiency anemia
What does a high folic acid result mean?
High folate is usually due to supplements or a folate-rich diet and generally does not indicate a problem.
- Folic acid supplements or multivitamins
- Fortified foods or a diet rich in leafy green vegetables
- Eating shortly before the test
- B12 deficiency (folate builds up in the blood because cells can't use it)
What does a low folic acid result mean?
Low folate is linked to low intake or increased needs; if prolonged it can cause anemia, and it matters for the baby's development in pregnancy.
- Diet low in leafy greens, legumes and fruit
- Increased needs during pregnancy and breastfeeding
- Regular alcohol use
- Certain medicines (e.g., methotrexate, some epilepsy drugs)
- Absorption problems such as celiac disease
- Anemias with increased red cell breakdown (hemolytic anemia)
My result is outside the reference range. What should I do?
Serum folate reflects recent diet, so fasting before the test is recommended. Interpret it together with B12, and talk to your doctor if you are planning a pregnancy.
Reference ranges depend on the method, age and sex; always use the range printed on your report. This information is for general guidance only; consult your doctor for diagnosis and treatment.
