A Folate (Vitamin B9) test measures the level of this essential B vitamin in your blood. Folate is critical for DNA synthesis, cell division, and red blood cell formation. Deficiency is particularly dangerous during pregnancy.
What This Test Measures
Serum Folate:
The level of folate circulating in your blood. Folate is the natural form found in food; folic acid is the synthetic form in supplements. Both are measured by this test.
Reference Range
Normal: Greater than 3.0 ng/mL (ranges vary by laboratory)
Who Should Consider This Test
• Women planning pregnancy or who are pregnant
• Macrocytic anemia (large red blood cells)
• Symptoms of deficiency (fatigue, weakness, mouth sores)
• Malabsorption conditions (celiac, Crohn’s)
• Alcoholism
• Elderly at risk for nutritional deficiency
• Taking medications that affect folate (methotrexate, anticonvulsants)
Why Folate Matters
Cell Division & DNA:
Folate is essential for creating new cells, making it crucial during periods of rapid growth.
Pregnancy:
Adequate folate before and during early pregnancy prevents neural tube defects (spina bifida, anencephaly). Women need 400-800 mcg daily.
Red Blood Cell Formation:
Deficiency causes megaloblastic anemia with large, immature red blood cells.
Symptoms of Deficiency

• Shortness of breath
• Pale skin
• Irritability
• Mouth sores and tongue swelling
