Title: Schilling evaluation of pernicious anemia: current status

Abstract

The Schilling examination remains a popular means of evaluating in vivo absorption of vitamin B/sub 12/. When absorption is abnormally low, the test may be repeated with addition to exogenous intrinsic factor (IF) in order to correct the IF deficiency that characterizes pernicious anemia. A dual-isotope variation provides a means of performing both stages of the test simultaneously, thereby speeding up the test and reducing dependence on complete urine collection. In vivo studies indicate that, when administered simultaneously, the absorption of unbound B/sub 12/ is elevated, and IF-bound B/sub 12/ is reduced, in pernicious-anemia patients, relative to the classic two-stage examination. A number of clinical studies indicate significant difficulty in resolving clincial diagnoses with the dual-tracer test. An algorithm is offered for selecting the most suitable variation of the Schilling test to improve the accuracy of test results and the ease of performance.
