Vitamin B9 (Folic Acid / Folate )

The Vitamin B9 Test measures the level of folate (folic acid) in your blood. Folate is a B-vitamin essential for red blood cell production, DNA synthesis, and proper development of the fetal nervous system during pregnancy.

• To detect folate (vitamin B9) deficiency

• To evaluate megaloblastic anemia (caused by low folate or B12)

• To monitor folate levels in pregnant women or those with malabsorption conditions

• To investigate symptoms like:

  • Fatigue

  • Pale skin

  • Mouth sores

  • Irritability or difficulty concentrating

Sample Required:
A blood sample

Fasting Required:

Fasting for 8–12 hours is recommended.

• Low folate levels may indicate:

  • Poor diet (common in alcoholism or low-vegetable intake)

  • Malabsorption (e.g., celiac disease, Crohn’s disease)

  • Increased needs (pregnancy, certain diseases)

  • Use of certain medications (e.g., methotrexate, anticonvulsants)

• High folate levels may result from supplementation; not usually harmful but can mask a B12 deficiency.
