The Folate (Serum) test measures the level of folate in the blood. Folate is a B-vitamin that is essential for the production and maintenance of new cells, including red blood cells. This test is used to evaluate folate deficiency or excess in the body.

Folate deficiency can contribute to the diagnosis of certain health conditions, such as:

1. Megaloblastic anemia: Folate deficiency can lead to the production of abnormally large red blood cells, causing megaloblastic anemia.
2. Malabsorption disorders: Conditions that affect the absorption of nutrients in the gastrointestinal tract, such as celiac disease or inflammatory bowel disease, can lead to folate deficiency.
3. Alcoholism: Chronic alcohol consumption can interfere with folate absorption and utilization, leading to deficiency.
4. Pregnancy complications: Folate deficiency during pregnancy can increase the risk of neural tube defects in the developing fetus.
