| Popis: | The newly developed rapid diagnostic test (RDT, DK14-CA1, Denka Seiken Co., Ltd.) to detect Campylobacter antigen was evaluated using fecal specimens of patients with enteritis. The RDT is an immunochromatographic assay using colored latex and can detect Campylobacter antigen (C. jejuni and C. coli) from patients' stool samples within 15 minutes. A total of 227 stool samples obtained from patients with enteritis were examined and the results were compared with conventional culture methods. Overall sensitivity, specificity, accuracy and positive predictive value (PPV) were 75.6%, 98.6%, 89.9% and 97.0% respectively. Among 53 severe cases defined with their clinical findings, sensitivity, specificity, accuracy and PPV were 82.1%, 100%, 90.6% and 100% respectively. Mean time to obtain the result with the RDT was 7 minutes whereas the culture method took 2.2 days. This study revealed the usefulness of the newly developed RDT as a rapid detection tool for Campylobacter antigen. Although the RDT has a little lower sensitivity compared with culture method, the simple and rapid test can contribute to treatment decisions for patients with enteritis and can be used at the patient's bedside and in outpatient clinics. |
