Der Einfluß einer Vitamin B12-Prämedikation auf das Ergebnis des Schilling-Tests

Summary The effect of previous administration of vitamin B12 on the Schilling test was examined in 10 patients, repeating the test during and 10 days after vitamin B12 treatment. Under vitamin B12 medication, the patients showed a significantly decreased vitamin B12 urinary excretion. Ten days after vitamin B12, repeat Schilling test demonstrated comparable results with baseline values except for one patient, who persistently had a low value. Our study shows that Schilling tests should not be performed at least during the first 10 days after vitamin B12 medication.
