OPS-Code 3-70b.1:
Scintigraphy: Radionuclide tests of absorption and excretion: Schilling test
You had a Schilling test.
The Schilling test is used to measure how much vitamin B12 is absorbed by your small intestine.The intestines are made up of the small intestine and the large intestine or colon. The small intestine connects to the stomach. The nutrients are absorbed into the blood from the food in the small intestine.Vitamin B12 is absorbed in the small intestine. It is an important substance for the production of red blood cells.
Radioactively labeled (radiolabeled) vitamin B12 is used for the Schilling test. The radiolabeled vitamin B12 is swallowed and reaches the kidneys via the small intestine and blood vessels. The kidneys excrete the radiolabeled vitamin B12 in the urine. Urine is collected over a period of 24 hours. The collected urine is then tested to measure how much radiolabeled vitamin B12 was excreted. This makes it possible to determine whether the small intestine is absorbing sufficient quantities of vitamin B12. If the small intestine is absorbing less vitamin B12 than normal, the collected urine will also contain a smaller amount of radiolabeled vitamin B12.
