Test Details
Turnaround Time
2 - 5 days
Use
High-risk HPV test is used for types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68, without differentiation of the individual type. If the initial high-risk test is positive, then the residual specimen will be tested for HPV types 16 and 18,45; type 18 cannot be differentiated from type 45.
Limitations
A negative result does not exclude the possibility of an HPV infection since very low levels of infection or sampling error may produce a false-negative result.
Methodology
Nucleic acid amplification (NAA)

Specimen Requirements
Information on collection, storage, and volume
Specimen
Cervical cells in liquid-based cytology transport
Volume
ThinPrep® vial
Minimum Volume
A minimum volume cannot be determined for the ThinPrep® vial because it varies depending on the cellularity of the specimen.
Container
ThinPrep® vial
Storage Instructions
Maintain specimen at room temperature. Specimens in ThinPrep® vials must be processed within 21 days of collection for HPV.
Causes for Rejection
Improper collection; inadequate specimen; improper labeling; specimen leaked in transit; quantity not sufficient for analysis; name discrepancies; specimen submitted on male patient; specimen submitted in vial that expired according to manufacturer's label; frozen specimen; SurePath™ vial. For HPV: specimen more than 21 days old in ThinPrep® vial.
Collection
ThinPrep® Vial − Broom or Brush/Spatula
Broom-like collection technique: Obtain a sample from the cervix using a broom-like device by inserting the brush portion into the cervical os and then rotate the brush five times. Rinse the collection device in the PreservCyt® solution by pushing the brush into the bottom of the vial 10 times, forcing the bristles to bend apart to release the cervical material. As a final step, twirl the brush between the thumb and forefinger vigorously to release additional cellular material. Discard the collection device. Tighten the cap on the ThinPrep® vial so that the torque line on the cap passes the torque line on the vial.
Brush/spatula technique: Insert the brush into the endocervical canal until only the bottommost fibers are exposed. Slowly rotate the brush ¼ to ½ turn in one direction. Do not over-rotate the brush. Then, rotate the brush in the PreservCyt® solution 10 times while pushing against the wall of the ThinPrep® vial. Swirl the brush vigorously to release additional material. Discard the brush. Obtain an adequate sample from the ectocervix using a plastic spatula. Swirl vigorously in the ThinPrep® vial 10 times and discard the spatula. Tighten the cap on the ThinPrep® container so that the torque line on the cap passes the torque line on the vial.
