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.
Select the Schilling Test button or press Alt+S on Figure 10-1 Lab Tests Main Screen.
