Laboratory: Clinical Microbiology
Test Name:
Test Code: TVA
Clinical Information:
Test Indications:
Female patient experiencing vaginal discharge that may be foul smelling and pruritus.

The results obtained with this test must be used only as adjunct to other information available to the clinician.
A negative result may be obtained if the specimen collection is inadequate or if antigen concentration is below the sensitivity of the test.
This test does not differentiate between viable and non-viable organisms.
Patients with vaginitis/vaginosis symptoms may have mixed infections.  Therefore, a testing indicating the presence of T. vaginalis does not rule out the presence of Candidiasis or Bacterial vaginosis.
Routine screening for T. vaginalis infection is not advised for asymptomatic persons without HIV infection who do not have risk factors.
