Test Identifier Information

 
Registration CodeTVPC
Method

Real-time PCR for T.vaginalis RNA using Automated Alinity m platform.

Diagnostic Use / Indications

Trichomonas vaginalis is a common cause of sexually acquired infections which in women can be non-specific, but may include vaginal discharge, vaginitis, cervicitis and irritation. Between 70-85% of patients infected with T.vaginalis are asymptomatic. Infections in pregnancy may result in sequelae such as preterm labour and premature rupture of membranes. In men T.vaginalis is an important cause of urethritis.

Microscopic evaluation of wet mount preparations and Rapid immunochromatographic tests are no longer routinely performed as Nucleic acid amplification tests have are now more rapidly available to be performed and are the preferred method of TV infection due to superior sensitivity and excellent specificity.

Specimen Collection

 
Pre-Testing Requirements

T. vaginalis is required to be specifically requested. 

Sample collection remains the same for other molecular STI testing using the specific collection device: See Specimen collection protocol.

Specimen Collection Protocols

Swab guide 

Testing guidelines for referral of Trichomonas vaginalis.

Sample collection is as per STI chlamydia trachomatis / NG protocol.

Must use: Abbott Alinity m multi collect specimen collection kit (orange cap). Use the swabs provided with this collection kit. Please use the disposable transfer pipette for aliquoting urines to the collection device. Fill urine to the clear "Fill window" on the tube.

Swabs in Amies transport media are UNSUITABLE for PCR.

Samples: Urethral, Vaginal, cervical, first catch urines.

The collection devices are available from  Customer services Canterbury Health Laboratories LabInfo@cdhb.health.nz or 0800 THE LAB (843 522).

Detected

Not detected

Interpretation

"T.vaginalis DNA detected" indicates the presence of T.vaginalis in the sample.

"T.vaginalis DNA not detected indicates that T.vaginalis was not present in the sample or at levels lower than the assays detection level.

PCR inhibitors detected indicates an invalid negative PCR result and a repeat sample may be required.

Uncertainty of Measurement

Analytical sensitivity ( manufacturers)

Urogenital samples TV: 0.02 Trophozoite (TV)/assay.

Additional Information

Do not submit swabs in bacterial transport  media for PCR.  

Optimal performance of this test requires appropriate and correct collection and handling.

Performance of the assay for the detection of TV and MG has not been established for oropharyngeal or rectal swab specimens.
