Question

Quizplus · Accepted Answer

Schilling test is a diagnostic test for vitamin B₁₂ malabsorption. The test is performed by administering a small amount of radioactive B₁₂ orally, followed by an injection of nonradioactive B₁₂. The amount of radioactive B₁₂ and its metabolites excreted in the urine over a period of time is measured. If the body is unable to absorb B₁₂, then the radioactive B₁₂ will not be excreted in urine. The Schilling test is used to diagnose malabsorption of vitamin B₁₂, which is necessary for the production of red blood cells and nervous system function. The test involves giving the patient radioactive vitamin B₁₂ and then measuring the amount that is excreted in the urine. If the majority of the vitamin B₁₂ is excreted, this indicates that it is not being absorbed properly.
