This test is ideal if you're experiencing unexplained fatigue, weakness, or signs of anemia like paleness or shortness of breath. It measures red blood cell folate levels to identify nutritional deficiencies that may be affecting your energy, blood cell production, and overall health. Many people use this test when they suspect vitamin deficiency is causing their symptoms, especially if they have digestive issues, are pregnant, or have dietary restrictions.
You should not take any vitamins or supplements containing folic acid for three to five days before your test, though you should consult your physician before discontinuing any supplements. If you're taking high-dose biotin (vitamin B7 or B8), stop taking it at least 72 hours before your blood draw, as it can interfere with test results. No fasting is required for this test.
This test measures Folate RBC (Red Blood Cell Folate), which provides a more accurate picture of your long-term folate status compared to serum folate. RBC folate levels remain fairly constant and reflect your body's stored folate over the past 2-3 months, making it especially useful for diagnosing true nutritional deficiencies. This measurement is particularly important for pregnant women, those with absorption issues, and anyone experiencing symptoms of anemia or chronic fatigue.
What this means
Your red blood cell folate levels are slightly below the optimal range, which may indicate a long-term folate deficiency. While not critically low, this could contribute to fatigue, weakness, and reduced energy levels over time. Low folate can also affect red blood cell production and overall cellular health.
Recommended actions
Increase intake of folate-rich foods like dark leafy greens, legumes, and fortified cereals
Consider a daily folic acid supplement after consulting with your healthcare provider
Limit alcohol consumption, as it interferes with folate absorption
Retest in 8-12 weeks after making dietary changes or starting supplementation
