To evaluate the performance of the Hologic Gen-Probe (San Diego, CA) PANTHER system.
The performance of PANTHER was compared with the Hologic Gen-Probe TIGRIS and/or Roche (Indianapolis, IN) COBAS AMPLICOR systems through testing of patient specimens and the spiked-urine matrix.
After discrepant resolution, PANTHER demonstrated a 99.3% (95% confidence interval [CI], 96.0%-99.9%) positive and 100% (98.5%-100.0%) negative agreement for Chlamydia trachomatis (CT) and 100% (96.6%-100.0%) positive and 100% (98.6%-100.0%) negative agreement for Neisseria gonorrhoeae (NG) for all male, female, unsexed, and NG-spiked female urine specimens combined. For other specimen types collectively, the PANTHER demonstrated 100% (95% CI, 90.6%-100.0%) positive and 100% (88.3%-100.0%) negative agreement for CT and 90.9% (62.8%-98.4%) positive and 100% (93.5%-100.0%) negative agreement for NG. Analytical sensitivity of the PANTHER in urine matrix was similar to the TIGRIS system.
The PANTHER system provides an excellent new addition to options for detecting CT and NG, is appropriate for testing urine samples, and will facilitate high-throughput testing in the clinical laboratory.
