SCHILLING TEST
The Schilling Test is used to determine B-12 deficiencies from either malabsorption, lack of
intrinsic factor (pernicious anemia), or intraintestinal destruction. It entails oral administration
of Cobalt 57 labeled Vitamin B-12 to the patient. Thereafter, the urine is collected for 24 or 48
hours. The ratio of excreted to administered Co57 is calculated. If the initial results indicate a
reduced amount of excreted vitamin, the test is repeated with a second sample of labeled B-
12 and intrinsic factor. For Schilling Test I, abnormal results are generally less than 8%-10%.
Normal range is generally 11% to 26%. For Schilling Test II, no change indicates
malabsorption, while an improved percentage indicates pernicious anemia.
Note: The exact normal range for excretion for your facility and patients should be
independently determined according to the guidelines provided by the Schilling Test
kit manufacturer.
