What Does the RBC, Folate Blood Test Measure?

This blood test evaluates folate or vitamin B9, an essential nutrient for RBC or erythrocyte production, fetal development, cell growth, as well as protein and DNA synthesis. Folates are derived from dietary sources. Its deficiency can be attributed to inadequate consumption of folate-rich foods or digestive problems involving nutrient malabsorption.

Who Should Take an RBC Folate Test?

Individuals showing the following symptoms of folate deficiency are advised to take the folate RBC blood test:

  • Fatigue
  • Diarrhea
  • Headache
  • Mouth ulcers
  • Muscle weakness
  • Irregular heartbeat
  • Difficulty breathing
  • Depression and confusion
  • Paraesthesia (tingling and pricking)

Pregnant women, in particular, should monitor folate levels as insufficient intake or absorption of this nutrient can lead to neural tube defects. Also, those who are already undergoing supplementation will need to take the test to monitor if the treatment is effective.

Red Blood Cell Folate Level Test Preparation

Don’t take vitamin B9 or folate three to five days before the test.

RBC Folate Lab Test Results

The normal laboratory values for folate, RBC may vary depending on the laboratory where the test was performed and the methods used for the test. You will usually receive a reference interval with an upper and lower limit. Your test results suggest normal serum folate levels if they fall within the range.

Low folate is a common concern due to its association with several conditions, including megaloblastic and macrocytic anemias (characterized by high mean corpuscular volume or MCV). You will likely take a complete blood count (CBC) to assess your RBC production further.
