Repeat stool testing for<i>Clostridium difficile</i>using enzyme immunoassay in patients with inflammatory bowel disease increases diagnostic yield

Abstract

Approximately one in five IBD patients with CDI required repeat testing to yield a positive result with EIA. There are minimal diagnostic gains of repeat testing by EIA or PCR in patients without IBD. We recommend repeat stool testing for CDI when using EIA to increase diagnostic yield in IBD patients.
