Preferred Specimen
Specimen source is required.
Submit only 1 of the following specimens
Broom Collection Device
Specimen Type: Cervical (endocervical or ectocervical)
Collection Container: ThinPrep/PreservCyt vial
Specimen Volume: 20 mL of solution in ThinPrep/PreservCyt vial
Endocervical Brush/Spatula Collection Device
Specimen Type: Ectocervix and endocervix
Collection Container: ThinPrep/PreservCyt vial
Specimen Volume: 20 mL of solution in ThinPrep/PreservCyt vial
Instructions
Broom Collection Device
- Obtain adequate sampling from cervix using a broom-like collection device. If desired, use lukewarm water to warm and lubricate the speculum. Insert the central bristles of the broom into the endocervical canal deep enough to allow the shorter bristles to fully contact the ectocervix. Push gently and rotate the broom in a clockwise direction 5 times.
- Rinse the broom as quickly as possible into the PreservCyt solution vial by pushing broom into bottom of vial 10 times, forcing the bristles apart.
- As a final step, swirl broom vigorously to further release material. Discard the collection device.
- Tighten cap on vial so that the torque line on the cap passes the torque line on the vial.
- Specimen vial must be labeled with a minimum of 2 unique identifiers (patient's name and medical record number or date of birth).
- Bag ThinPrep specimens individually as they have a tendency to leak during transport.
- Place labels on the vial and on the bag.
- Obtain an adequate sampling from the ectocervix using a plastic spatula. If desired, use lukewarm water to warm and lubricate the speculum. Select contoured end of plastic spatula and rotate it 360 degrees around the entire exocervix while maintaining tight contact with exocervical surface.
- Rinse spatula as quickly as possible into the PreservCyt solution vial by swirling spatula vigorously in vial 10 times. Discard the spatula.
- Next, obtain an adequate specimen from endocervix using an endocervical brush device. Insert the brush into the cervix until only the bottommost fibers are exposed. Slowly rotate 1/4 or 1/2 turn in one direction. Do not over-rotate.
- Rinse the brush as quickly as possible in the PreservCyt solution by rotating the device in the solution 10 times while pushing against the PreservCyt vial wall.
- Swirl brush vigorously as final step to further release material. Discard the brush.
- Tighten the cap so that the torque line on the cap passes the torque line on the vial.
- Specimen vial must be labeled with a minimum of 2 unique identifiers (patient's name and medical record number or date of birth).
- Bag ThinPrep specimens individually as they have a tendency to leak during transport.
- Place labels on the vial.

Limitations
The performances of this test, including reference range and other method performance specifications for this assay, has not been evaluated in patients younger than 14 years of age.
Results depend on adequate specimen collection, absence of inhibitors, and sufficient DNA for detection.
This test should not be used to determine therapeutic success as nucleic acids may be present, and detected, after antimicrobial therapy.
A negative result does not necessarily rule out infection. Specimens containing mucus, gels, lubricants, or creams may give invalid or false negative results.
