EPIC Test Procedure Code: LAB4025

Performing Lab:
Referral Laboratory
Container Type:
Gen-Probe APTIMA swab; CytycThinPrep or TriPath SurePath liquid cytology vial
Specimen Type:

Submit one of the following:
1. One swab: vaginal, endocervical, or male urethral (Gen-Probe APTIMA swab)
2. Cervical cells in liquid cytology vial (CytycThinPrep or TriPath SurePath liquid cytology vial)

For urine see Trichomonas vaginalis Detection urine

Preferred Volume:
One swab; entire liquid cytology vial
Collection Procedure:

Vaginal swab: Collect vaginal fluid sample using the Gen-Probe APTIMA vaginal swab kit by contacting the swab to the lower third of the vaginal wall and rotating the swab for 10-30 seconds to absorb fluid. Immediately place the swab in the transport tube and carefully break the swab shaft against the side of the tube. Tightly screw on the cap.

Endocervical swab: Remove excess mucus from the cervical os and surrounding mucosa using the cleaning swab (white-shaft swab in the package with red printing). Discard this swab. Insert the specimen collection swab (blue-shaft swab in the package with green printing) into the endocervical canal. Gently rotate the swab clockwise for 10-30 seconds in the endocervical canal to ensure adequate sampling. Withdraw the swab carefully, avoid contact with the vaginal mucosa. Remove the cap from the swab specimen transport tube and immediately place the specimen collection swab into the transport tube. Carefully break the swab shaft at the scoreline, using care to avoid splashing of the contents. Recap the swab specimen transport tube tightly.

Male urethral swab: The patient should not have urinated for at least one hour prior to specimen collection. Insert the specimen collection swab (blue-shaft swab in the package with the green printing) 2-4 cm into the urethra. Gently rotate the swab clockwise for 2 to 3 seconds in the urethra to ensure adequate sampling. Withdraw the swab carefully. Remove the cap from the swab specimen transport tube and immediately place the specimen collection swab into the specimen transport tube. Carefully break the swab shaft at the scoreline, using care to avoid splashing of the contents. Recap the swab specimen transport tube tightly.
