Vitamin B12 Testing

B12, Cobalamin, True
Sample Report
Specimen Type: Blood


This Vitamin B12 test may be used to determine B12 Vitamin deficiency or macrocytic anemia. Vitamin B12 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. Turnaround time for the Vitamin B12 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 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.
