Folate Blood Tests

The test measures the level of folate, also known as vitamin B9, in the blood serum. Folate is an essential nutrient that plays a crucial role in DNA synthesis, red blood cell production, and cell division.

Someone may have this test done for several reasons:

1. To diagnose folate deficiency: Low levels of folate in the blood can indicate a deficiency, which can lead to symptoms like fatigue, weakness, pale skin, and difficulty concentrating.

2. To monitor folate levels during pregnancy: Adequate folate levels are crucial during pregnancy to prevent neural tube defects in the developing fetus. This test helps ensure that the pregnant individual has sufficient folate levels.

3. To assess the effectiveness of folate supplementation: Individuals who are taking folate supplements or undergoing treatment for folate deficiency may have this test to monitor the response to treatment and adjust the dosage if needed.

4. To investigate certain medical conditions: Folate levels can be affected by certain medical conditions like malabsorption disorders, liver disease, alcoholism, and certain medications. This test can help identify the underlying cause of abnormal folate levels in such cases.
