Qualitative detection of oral, rectal and genitourethral Neisseria gonorrhoeae colonization.

Neisseria gonorrhoeae is a common sexually transmitted disease organism broadly disseminated throughout the world. InTray GC is a fully enclosed microbiology cassette, which enables sample collection, transport, culture and identification in a single unit. The proprietary modified Thayer Martin agar is selective for gonococcal bacteria. Results can be interpreted after 24-72 hours incubation. InTray GC is a single exposure culture system with dynamic built-in components and features that are designed for user compatibility and ease of detection.

Time to Result

Incubate InTray GC flat to avoid moisture leaking into the CO2 pill chamber. Incubate the tray right side up for 24–72 hours at 35°C (95°F) under ambient atmosphere.

If InTray GC is being used for transport, to any laboratory located outside of the facility where collection was performed, then pre-incubation at 35°C for 24 hours is required.

After the pre-incubation step, InTray GC can be transported up to 72 hours at ambient temperature (18-25°C) to the testing laboratory for analysis.


  • Extended 12 month shelf life from the date of manufacture
  • InTrayGC is compatible with storage at room temperature. However, for optimal performance store at 2-8˚C
  • Do not freeze.
  • InTray GC can be transported up to 72 hours at ambient temperature (18-25°C) to the testing laboratory for analysis.
  • Oral swab
  • Rectal swab
  • Genitourethral swabs
  • Pharyngeal Swab
