Folate RBC Blood Test


Test Code: 266015
Specimen Type: Blood

Description:

Folate RBC Blood Test

This test measures the level of Folate in Red Blood Cells.  Folate is a vitamin which is part of the B complex series.  It plays an important role if a number of bodily functions including the production of red blood cells.  Folate cannot be produced by the body so it must come from a person's diet.  Foods which are high in folate include green leafy vegetables, citrus, liver, and beans.  Deficiency in folate can result in several forms of anemia.  Testing for Folate levels in RBC's can be more effective than a regular blood test.  Serum folate levels can be affected by a person's recent diet.  The concentration of folate in red blood cells is often considered a more accurate measurement of true folate levels in the body's tissues.  The Folate RBC test also includes a measurement for Hematocrit, the percentage of the blood which is made up of red blood cells. 

A Folate RBC test is sometimes ordered along with a Folate Blood test or as a followup to irregular results from a blood test.  A Vitamin B12 test is often ordered along with folate due to the connected roles these vitamins play in the body.

Turnaround for this test is typically 1-3 business days.  

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.

Requirements:

Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For people receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For people on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
