What is it indicated for?
The BD ProbeTec ET Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) Amplified DNA Assays, when tested with the BD ProbeTec ET System, use Strand Displacement Amplification (SDA) technology for the direct, qualitative detection of Chlamydia trachomatis and Neisseria gonorrhoeae DNA in endocervical swabs, male urethral swabs, and in female and male urine specimens as evidence of infection with C. trachomatis, N. gonorrhoeae, or of co-infection…

The BD ProbeTec ET Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) Amplified DNA Assays, when tested with the BD ProbeTec ET System, use Strand Displacement Amplification (SDA) technology for the direct, qualitative detection of Chlamydia trachomatis and Neisseria gonorrhoeae DNA in endocervical swabs, male urethral swabs, and in female and male urine specimens as evidence of infection with C. trachomatis, N. gonorrhoeae, or of co-infection with both C. trachomatis and N gonorrhoeae. Specimens may be from symptomatic or asymptomatic females and males. A separate Amplification Control is an option for inhibition testing (BD ProbeTec ET CT/GC/AC Reagent Pack). The BD ProbeTec ET CT/GC assays may be performed using either the BD ProbeTec ET System or a combination of the BD ProbeTec ET System and BD Viper instrument.
The BD Viper System, when used with BD ProbeTec ET amplified nucleic acid assays, is intended for the in vitro detection of targeted organisms from specimens as identified in the assay-specific reagent package insert(s).
Indications for use as stated in the FDA summary.
