SCHILLING TEST
To perform a Schilling Test, select the SCHILLING TEST button from the LAB TESTS Main
screen. Figure 8-2 will appear. The Schilling Test utilizes Cobalt 57 labeled Vitamin B-12
and is used to determine B-12 deficiencies from either malabsorption, lack of intrinsic factor
(pernicious anemia), or intraintestinal destruction. The test entails collection of urine for 24
or 48 hours after the oral administration of radioactive labeled vitamin B-12. 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 precise normal range for your facility and patient population should be
independently determined by following guidelines provided by the Schilling Test Kit
manufacturer.
