Comparison of chemiluminescent DNA probe to cell culture for the screening of Chlamydia trachomatis in a gynecology clinic population.
Two hundred ninety-five endocervical swab specimens were obtained from patients presenting to a gynecology clinic in order to compare a nonradioactive chemiluminescent DNA probe with cell culture for detection of Chlamydia trachomatis. Discrepancies between cell culture and DNA probe were resolved by retesting and reculturing samples. In a population with a 10.8% prevalence, the corrected sensitivity, specificity, positive predictive value, and negative predictive value for the DNA probe were 80.6, 95.8, 71.4, and 97.3%, respectively. These results compare favorably to other non-culture methods such as direct fluorescent antibody and enzyme immunoassay tests for the detection of C trachomatis in populations with similar prevalence rates.
