| schilling test | <investigation> This test measures the amount of vitamin B12 in the urine after ingesting a dose of B12. This test evaluates vitamin B12 absorption. The cells in the stomach produce a substance known as intrinsic factor. This substance combines with B12 to allow absorption in the distal ileum. The patient is given a small dose of radioactive B12 which can then be detected in the patients urine. Pernicious anaemia is the clinical result of B12 deficiency. Conditions that can result in an abnormal Schilling test include: deficiency of intrinsic factor, malabsorption or the development of an antibody to intrinsic factor. The Schilling test can be performed with or without administration of intrinsic factor to determine what the underlying cause for pernicious anaemia. Laxative use, renal insufficiency and hypothyroidism can all interfere with the results of this test. (27 Sep 1997) |

| Schilling t. |
(for gastrointestinal absorption of vitamin B12): a measured amount of radioactively labeled cyanocobalamin is given orally, followed by a parenteral flushing dose of the nonradioactive vitamin, and the percentage of radioactivity is determined in the urine excreted over a 24-hour period. The test is usually performed three times: first with added intrinsic factor, then without it, and then after antibiotic therapy. The results are used in the diagnosis of pernicious anemia and other disorders of vitamin B12 metabolism.
