What is it indicated for?

The cobas® CT/NG Test is an in vitro nucleic acid amplification test that utilizes Polymerase Chain Reaction (PCR) and nucleic acid hybridization for the qualitative detection of Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) DNA to aid in the diagnosis of chlamydial and gonococcal disease. The test may be used with vaginal swab specimens self-collected in a clinical setting and male urine from both symptomatic and asymptomatic individuals.…

The cobas® CT/NG Test is an in vitro nucleic acid amplification test that utilizes Polymerase Chain Reaction (PCR) and nucleic acid hybridization for the qualitative detection of Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (NG) DNA to aid in the diagnosis of chlamydial and gonococcal disease. The test may be used with vaginal swab specimens self-collected in a clinical setting and male urine from both symptomatic and asymptomatic individuals. Specimens to be tested should be collected in cobas® PCR Media.

The cobas® PCR Female Swab Sample Kit is used to collect and transport self-collected vaginal swab specimens in a clinical setting. The cobas® PCR Media serves as a nucleic acid stabilizing transport and storage medium for gynecological specimens. Use this collection kit only with the cobas® CT/NG Test. NOTE: This collection kit should not be used for collection of alternative gynecological specimens.

The cobas® PCR Urine Sample Kit is used to collect and transport male urine specimens. The cobas® PCR Media serves as a nucleic acid stabilizing transport and storage medium for urine specimens. Use this collection kit only with the cobas® CT/NG Test. NOTE: This collection kit should not be used for collection of female urine specimens.

Indications for use as stated in the FDA summary.
