Clue cell exam; Trichomonas exam; yeast exam


Presumptive diagnosis of Trichomonas vaginalis infection


Microscopic evaluation

Specimen Requirements


Vaginal swab, sedimented first-void male urine, semen, prostatic fluid, or male urethral swab


Swab or one to two drops of fluid or sedimented urine


InPouch™ TV transported at room temperature (for as long as 48 hours)


Specimens are inoculated directly into the culture media with the exception of urine specimens which are first centrifuged at 500xg and the sediment used for inocula. Collect specimens using a cotton swab. To avoid leakage, first move the medium at the top of the InPouch™ downward to the middle of the upper chamber. Tear off plastic above the white closure. In order to admit the swab, open the InPouch™ by pulling the closure tape's middle tabs apart. Insert swab into upper chamber medium of the InPouch™ TV and elute specimen by rubbing swab between the InPouch™ TV walls. Remove the swab and discard. Liquid specimens are added directly to the upper chamber medium of the InPouch™ TV. When specimen inoculation is completed, squeeze the top of the InPouch™ closed, then roll down three rolls and fold tabs over. Keep InPouch™ in an upright position.

Causes for Rejection
