Intrinsic factor is a protein produced by cells in the stomach lining. The body needs it so the intestines can absorb vitamin B12 efficiently.Stage II of the test can tell whether low vitamin B12 levels are caused by problems in the stomach that prevent it from producing intrinsic factor.If a Stage II test is abnormal, a Stage III test is performed.Stage III: This test is done after you have taken antibiotics for 2 weeks.

With this test, you will take pancreatic enzymes for three days, followed by a radioactive dose of vitamin B12.How to prepare for the testDo not eat for 8 hours before starting the test, then eat normally for the next 24 hours.

Talk to your doctor about the meaning of your specific test results.What abnormal results meanLow 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 diseaseCeliac disease (sprue)Crohn's diseaseLiver diseasePancreatic diseaseWhat the risks areLocal reaction to vitamin injectionNauseaFeeling lightheadedReferencesAntony AC.

Is it ok to take B12 tablets?
Very few people are ever deficient in B12. a vitamin that occurs in meat, milk and other dairy product (such as eggs). Unless you are on a vegan diet, there should be no reason for you to be deficient in B12, and taking a B12 supplement will probably not prove beneficial. Consult your GP/family doctor before starting a B12 supplement. (Added note) People suffering from Chronic Anaemia cannot absorb vitamin B12 from their food, and B12 tablets are of no use. They need to have a B12 injection every 3 months.
