The RBC Folate test by Quest Diagnostics measures folate (vitamin B9) levels stored within red blood cells, offering a longer-term picture of folate status compared to serum testing alone. Because red blood cells reflect folate levels over their approximately 120-day lifespan, this test may help identify sustained deficiency or excess for those monitoring nutritional status, methylation support, or pregnancy-related nutrient needs.
Why It's Worth Considering: RBC folate is widely regarded as a more clinically meaningful marker than serum folate for assessing true tissue stores, making it a practical choice for practitioners and individuals tracking supplementation outcomes over time.
