Vitamin B12 and Folates Blood Test

Sample Report
Specimen Type: Blood


Vitamin B12 and Folates Blood Test

This test measures levels of Vitamin B12 and Folate (Folic Acid) 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 Macrocyotic 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 condition 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 are they are not getting enough in their diet.  It may take time for a person's body to deplete their 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.

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.


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.
