Comparative Study of Three Different Testing Mechanisms for Clostridium Difficile

July 19, 2011 updated by: Hamilton Health Sciences Corporation

Comparative Study of Enzyme Immunoassays:Techlab Toxins A&B, C Diff Quick Check for Glutamate Dehydrogenase (GDH);3 PCRs,and Cytotoxin Assay (CTA) for the Detection of Clostridium Difficile Toxin in Adult Stool Specimens

The purpose of this study is to establish which of the following tests perform best in diagnosing clostridium difficile. PCR, Enzyme Immunoassays (EIA) and C. difficile cytotoxin assay (CTA).

Study Overview

Status

Completed

Conditions

Detailed Description

This comparative study will be carried out in the hospital microbiology laboratory of a tertiary academic health center, St. Joseph's Healthcare (SJH) affiliated with McMaster University, Hamilton, ON on 500 individual stool samples from patients greater than 12 months of age to determine an efficacy of distinction between current gold standard and other methods of testing for Clostridium difficile. This study is required to find a faster test for diagnosis of CDI in order to facilitate prompt treatment and reduce the complications of CDI. Identification of infected cases will lead to the enforcement of infection control measures and thereby prevent spread to other susceptible children. This is turn will reduce costs, length of stay, morbidity, and mortality from CDI if instituted correctly.
