Sensitivity, but Not Specificity, of a Quantitative Immunochemical Fecal Occult Blood Test for Neoplasia Is Slightly Increased by the Use of Low-Dose Aspirin, NSAIDS, and Anticoagulants

Abstract

The use of aspirin/NSAIDS and anticoagulants was associated with a trend for increased sensitivity with no change in specificity for the detection of AAP/CRC. This study suggests that there is no need to stop these agents before I-FOBT testing.
