What is it indicated for?
The cobas liat CT/NG nucleic acid test is an automated, qualitative in vitro nucleic acid diagnostic test that utilizes real-time polymerase chain reaction (PCR) for the direct detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) nucleic acid in male urine and vaginal swabs, all in cobas PCR Media (Roche Molecular Systems, Inc.).
This test is intended as an aid in the diagnosis of urogenital infections in both symptomatic and asymptomatic individuals.
Indications for use as stated in the FDA summary.
