The serum folate test is an important diagnostic tool that measures the amount of folate, or vitamin B9, present in your blood. Folate plays a critical role in several bodily functions, including:
- DNA synthesis: Folate is essential for the production of DNA and RNA, which are necessary for cell division and growth.
- Red blood cell formation: Folate helps in the production of healthy red blood cells. A deficiency can result in macrocytic anemia, characterized by large, inefficient red blood cells.
- Cellular function and tissue growth: Folate is especially important during periods of rapid growth, such as pregnancy and infancy.
The importance of the serum folate test lies in its ability to detect folate deficiencies, which may occur due to:
- Dietary insufficiency: A lack of folate-rich foods, such as leafy greens, citrus fruits, and beans, can result in low folate levels.
- Pregnancy: During pregnancy, the body requires more folate to support fetal development.
- Malabsorption conditions: Diseases like celiac disease or Crohn’s disease can impair folate absorption.
Interpreting the results of a serum folate test can guide treatment:
- Low levels indicate folate deficiency, potentially requiring dietary supplementation or addressing the underlying condition.
- Normal levels suggest sufficient folate intake and absorption.
- High levels are rare but may occur in individuals taking high-dose folate supplements.
c) Recommended Tests:
- Vitamin B12 Test
This test checks the level of vitamin B12, which works closely with folate in red blood cell production and nerve health.

A CBC test can help evaluate the impact of folate deficiency on red blood cell size and count, offering a comprehensive view of anemia.
