Description
Folate (Rbc) (Fasting)
Sample Type:Whole Blood
Tests Included:
Measurement of Red Blood Cell (RBC) folate levels in the blood
Sample Required:
Blood sample
Test Time:
Results are typically available within a day or two.
Test Range Values:
Normal RBC folate levels range from 150 to 600 nanograms per milliliter (ng/mL).
What is the test?
This test measures the level of folate specifically within red blood cells, indicating the body’s folate levels over a more extended period than plasma folate levels.
Test Procedure:
A blood sample is drawn from a vein, and the concentration of RBC folate is measured in the laboratory.
When to take the test:
When investigating suspected folate deficiency or when evaluating certain anemias or neurological issues.
Who should take the test:
Individuals with symptoms of folate deficiency such as weakness, fatigue, or certain types of anemia may require an RBC folate test.
Precautions for exceptional cases:
Fasting may be required for accurate results. Follow the healthcare provider’s instructions regarding fasting before the test.
Frequently Asked Questions (FAQs) for Folate (RBC) (Fasting):
Q1: Why measure RBC folate instead of plasma folate?
A: RBC folate provides a more stable reflection of folate status in the body over a more extended period compared to plasma folate.
Q2: Can diet impact RBC folate levels?
A: Yes, folate-rich foods like leafy greens, legumes, and fortified cereals contribute to folate levels in the body.
Q3: What happens if RBC folate levels are low?
A: Low RBC folate levels may indicate folate deficiency, which can lead to anemia and neurological issues.
Q4: Can medications affect RBC folate levels?
A: Certain medications, like methotrexate or anticonvulsants, can interfere with folate metabolism and affect RBC folate levels.
Q5: Is folate testing routine during pregnancy?
A: Yes, folate levels are often monitored in pregnant individuals to prevent neural tube defects in the developing fetus.
