INTENDED USE

One Step T.V Ag test is used for the qualitative determination of Trichomonas vaginalis antigen from vaginal swabs.This test is intended for use in patients with symptoms of vaginosis/vaginitis or suspected exposure to the Trichomonas pathogen. 

SPECIMEN COLLECTION

1.Quality of testing specimen is crucial. Sufficient microorganism in the swabs should be guaranteed.

2.Collect the vaginal secretions from vaginal posterior dome using sterile swab.In absence of speculum, long swabs can also be used to collect the specimen from vaginal.

3.Put the swab into the sample tube if the specimen is to be tested immediately. If not, keep the specimen in a dry tube.The specimen can be stored for 72 hours at 2-8℃. For longer storage, specimen should be frozen at -20℃. Avoid freezing and thawing repeatedly.

4.Specimen processing:Add 20 drops of buffer vertically into the sample processing tube. Put the swab with specimen into the tube and rotate for 10 seconds to mix the reagents. After swallowing the sample in the tube for 2 minutes, wipe the swab along the tube wall, remove excess liquid and discard the swab. Cover the dipping tip of the processing tube.

TEST PROCEDURE

 The specimen,test kit and other testing materials should be brought and equillibrated to room temperature15-30℃prior to use.  Remove the test cassette from the pouch and use it as soon as possible.

Place the cassette on a clean surface. Make sure the tip of processing tube points downwards, squeeze the tube wall and add 2-3 drops of specimen into the sample well of the test cassette.

Wait for the pink colored lines to appear.Read result between 15-30 minutes. Do not read result after 30 minutes.

INTERPRETATION OF RESULTS

 

Positive

Two pink-colored lines appear in the result window,one is the test line, and the other is the control line. The color intensity of the test line may be weaker or stronger than that of the control line.

 

Negative

Only one pink colored line appears in the control region.No apparent pink line appears in the test region.

 

Invalid

Control line fails to appear. If the control line does not form, the test result is invalid and the assay should be repeated with a new device.
