The Utility of Repeated Stool Toxin Testing for Diagnosing Clostridium difficile Colitis
Abstract:Clostridium difficile is diagnosed using the enzyme-linked immunoassay (EIA) with the specificity and sensitivity ranging from 50–90% and 70–95%, respectively. Due to the wide ranges, there is considerable confusion regarding the value of the EIA toxin test. We undertook this study to evaluate the benefit of repeat stool toxin testing.
