Folic Acid, RBC

Description

The Folic Acid, RBC test measures the concentration of folic acid (vitamin B-9) within red blood cells. Unlike serum folate tests, which reflect recent dietary intake, the RBC folate test provides a more accurate picture of long-term folate status in the body. This is because red blood cells accumulate folate during their 120-day lifespan, making this test less susceptible to short-term fluctuations in folate intake. The test is crucial for diagnosing folate deficiency, which can lead to megaloblastic anemia and other health issues. It’s particularly valuable in assessing folate status in individuals with chronic conditions affecting nutrient absorption, pregnant women, and those on certain medications. Results from this test help healthcare providers determine the need for folate supplementation and monitor the effectiveness of treatment for folate deficiency.
