|---|---|
| Test Mnemonic: | TVAG |
| Specimen Requirements: | Female - endocervical swab, vaginal swab, liquid Pap (ThinPrep®) collection, urine Male - urine, urethral |
| Test Included: | Trichomonas nucleic acid assay |
| Collection: | Swabs - Follow the instructions found with the Aptima® collection kit for endocervical/vaginal specimens. Urine - Patient should not have urinated at least 1 hour prior to collection. Patient is instructed to collect a first-catch urine (approximately 20 to 30 mL of the initial urine stream) in a urine collection container free of any preservatives.

| Note: | A negative result does not completely rule out infection with T. vaginalis. Results should be interpreted in conjunction with other clinical data. This test is intended for medical purposes only and is not valid for the evaluation of suspected sexual abuse or for other forensic purposes. One sample may be submitted for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis testing. ThinPrep® specimens can be used for HPV, Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis testing.
