Schilling test

Alternate Names : Vitamin B12 absorption test

Normal Values

Urinating 8 - 40% of the radioactive vitamin B12 within 24 hours is normal.

Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

What do Abnormal Results Mean?

Low vitamin B12 levels can cause megoblastic anemia.

If there is a problem with the stomach's ability to make intrinsic factor, Stage I of the test will be abnormal and Stage II will be normal.

Both the Stage I and II Schilling tests will be abnormal in people who have problems absorbing vitamin B12 and intrinsic factor in the small intestine.

Abnormal results may be due:

Biliary disease
Celiac disease (sprue)
Crohn's disease
Liver disease
Pancreatic disease
