A self-contained broth media device

for the recovery and detection of Trichomonas vaginalis

InPouch® TV is a self-contained broth media device for the recovery and detection of Trichnomonas vaginalis from female vaginal samples or male urethra/urine samples. The selective, nutritive media provides presumptive-positive results of one or more live trichomonads under the microscope immediately after inoculation of specimen — while inhibiting the growth of other microorganisms, which can interfere with a reliable diagnosis.

Human trichomoniasis is a sexually transmitted infection (STI) caused by the flagellated protozoan Trichomonas vaginalis. It is recognized as one of the most prevalent sexually transmitted infections world-wide, in both males and females. The CDC estimates five million new cases occur in the U.S. annually.

Designed for user-friendly and convenient early culture confirmation detection of Trichnomonas vaginalis, InPouch consists of a high-barrier, oxygen-resistant plastic with two V-shaped-chambers connected by a narrow passage that provide a variety of benefits — and allows users to easily inoculate a specimen, immediately observe (wet mount) the specimen, store and/or transport (optional) before transferring to the lab for incubation and recording.


  • InPouch design enables collection, culture, and microscopic observation.  
  • Highly selective, culture media detection of Trichomonas vaginalis, in a cost-effective, easy to use, broth media device 
  • No plating or wet mount slide preparation needed — place directly on the microscope stage for low power (100x) observation.
