Vitamin B12 and Folates Testing

Sample Report
Specimen Type: Blood


The Vitamin B12 and Folates blood test may be used to determine Vitamin B12 or Folate deficiency or macrocytic anemia. Vitamin B12 and Folates deficiency may be caused by malnutrition, malabsorption disorders such as celiac disease, increased loss due to kidney or liver diseases and increased need due to pregnancy. Vitamin B12 is needed for normal red blood cell formation, as well as tissue and cellular repair. Folates are needed to red blood cell production and also needed to make DNA and RNA. Turnaround time for the Vitamin B12 and Folates 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.

Incubation Period:


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.
