## Indications for use
The cobas® CT/NG for use on the cobas® 6800/8800 Systems 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/or Neisseria gonorrhoeae (NG) DNA in male and female urine, clinician-instructed self-collected vaginal swab specimens (collected in a clinical setting), and clinician-collected vaginal swab specimens, endocervical swab specimens, oropharyngeal (throat) swab specimens and anorectal swab specimens all collected in cobas® PCR Media (Roche Molecular Systems, Inc.), and cervical specimens collected in PreservCyt® Solution. This test is intended as an aid in the diagnosis of chlamydial and gonococcal disease in both symptomatic and asymptomatic individuals. Ancillary Collection Kits The cobas® PCR Media Dual Swab Sample Kit is used to collect and transport human specimens. The cobas® PCR Media serves as a nucleic acid stabilizing transport and storage medium. Note: This kit has been validated for use with the following tests: • cobas® CT/NG v2.0 Test (for use on the cobas® 4800 Systems) • cobas® CT/NG for use on cobas® 6800/8800 Systems • cobas® TV/MG for use on the cobas® 6800/8800 Systems The cobas® PCR Media Uni Swab Sample Kit is used to collect and transport human specimens. The cobas® PCR Media serves as a nucleic acid stabilizing transport and storage medium. Note: This kit has been validated for use with the following tests: • cobas® CT/NG v2.0 Test (for use on the cobas® 4800 Systems) • cobas® CT/NG for use on cobas® 6800/8800 Systems • cobas® TV/MG for use on the cobas® 6800/8800 Systems • cobas® Cdiff Test for use on the cobas® 4800 System The cobas® PCR Urine Sample Kit is used to collect and transport urine specimens. The cobas® PCR Media serves as a nucleic acid stabilizing transport and storage medium. Note: This kit has been validated for use with the following tests: • cobas® CT/NG v2.0 Test (for use on cobas® 4800 Systems) • cobas® CT/NG for use on cobas® 6800/8800 Systems • cobas® TV/MG for use on the cobas® 6800/8800 Systems
