Vitamin B12 and Folates Blood Test (Labcorp)
This test measures levels of Vitamin B12 and Folate (Folic Acid), also known as Vitamin B9, in blood. B12 and Folate are important for red blood cell formation, DNA synthesis, and cell division. B12 deficiency can result in nerve damage as well as a condition known as Macrocytic Anemia in which Hemoglobin levels are lower than normal and Red Blood Cells are larger than normal. Folate deficiency can cause complications for a fetus during pregnancy. B12 and Folate deficiency is typically caused by malnutrition or malabsorption which may be caused by conditions such as Celiac Disease, bacterial or parasitic infection in the intestines, alcoholism, and certain types of medication. It is important to note that a person's B12 and Folate levels may show as normal even if they are not getting enough in their diet. It may take time for a person's body to deplete its stores of B12 and Folate enough to show a deficiency.
The Vitamin B12 and Folate test is typically ordered when a person is experiencing symptoms of anemia or neuropathy or has had abnormal results from Complete Blood Count (CBC). It may also be ordered when someone is undergoing treatment for B12 and Folate deficiency.
Turnaround for this test is typically 1 business day.

The Vitamin B12 and Folates test prefers a fasting period of 8-12 hours prior to collection. If the customer is unable to fast they must make it known at the time their order is placed. Specimen must be drawn before Schilling test, transfusions or B12 therapy is started.
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.
