Clinical study of the effectiveness of a dual amplified immunoassay (IDEIA PCE Chlamydia) for the diagnosis of male urethritis.
A clinical study of patients with male urethritis (n=316) was undertaken to determine the sensitivity potential for a new dual amplified immunoassay (IDEIA PCE Chlamydia). Increased sensitivity (98.8%, 84/85) was obtained for IDEIA PCE Chlamydia compared to a conventional antigen detection test (IDEIA Chlamydia, 81.2%, 69/85) when testing urine samples. In a smaller patient population (n=104) the positivity rate for the first-void urine tested with IDEIA PCE Chlamydia of 30.8% (32/104) was similar to the 27.9% (29/104) obtained from urethral swabs tested with a DNA probe assay (PACE 2). The increased sensitivity of the test was confirmed with a commercial PCR kit (Amplicor) and nested PCR. The IDEIA PCE Chlamydia kit has the sensitivity potential to be a clinically reliable alternative for detecting Chlamydia trachomatis.
