Test Code STHPV ThinPrep Screen with Human Papillomavirus (HPV) Reflex, Varies


Advisory Information


Mayo Clinic Laboratories' clients need prior laboratory approval to order Cytology testing.



Necessary Information


1. An acceptable cytology request form must accompany specimen containers and include the following: Patient's name, medical record number, date of birth, sex, source (exact location and procedure used), date specimen was taken, name of ordering physician and pager number.

2. Submit any pertinent history or clinical information.



Specimen Required


Patient Preparation: For optimal interpretation, Papanicolaou smears should be collected near the middle of the menstrual cycle. No douching, lubricant use, and sexual intercourse for 24 hours prior to specimen collection.

 

Only 1 aliquot may be removed from PreservCyt sample vial prior to performing the ThinPrep Pap Test, regardless of the volume of the aliquot (maximum aliquot volume: 4 mL).

 

Submit only 1 of the following specimens:

 

Supplies: Thin Prep Media with Broom Kit (T056)

Specimen Type: Cervical

Collection Container/Tube: ThinPrep

Specimen Volume: 16 mL

Collection Instructions:

1. 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.

2. 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.

3. As a final step, swirl broom vigorously to further release material. Discard the collection device.

4. Tighten cap on vial so that the torque line on the cap passes the torque line on the vial.

5. Specimen vial must be labeled with a minimum of 2 unique identifiers (patient's name and medical record number or date of birth).

 

Supplies: Thin Prep Media with Spatula and Brush Kit (T434)

Specimen Type: Ectocervix and endocervix

Collection Container/Tube: ThinPrep

Specimen Volume: 16 mL

Collection Instructions:

1. 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.

2. Rinse spatulas quickly as possible into the PreservCyt solution vial by swirling spatula vigorously in vial 10 times. Discard the spatula.

3. 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 one quarter or one half turn in 1 direction. Do not overrotate.

4. 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.

5. Swirl brush vigorously as final step to further release material. Discard the brush.

6. Tighten the cap so that the torque line on the cap passes the torque line on the vial.

7. Specimen vial must be labeled with a minimum of 2 unique identifiers (patient's name and medical record number or date of birth).

Testing Algorithm

When this test is ordered, a ThinPrep Pap screen will be performed. If the results include the criteria below, a high-risk human papillomavirus test will be performed:

-Atypical cells of undetermined significance (ASCUS), and the patient is 21 years or older

-Atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) and the patient is 21 years or older

-Low-grade squamous intraepithelial lesion (LSIL), and the patient is 50 years or older

-Inadequate endocervical/transformation zone component, negative for intraepithelial lesion or malignancy, and the patient is 30 years or older

If ThinPrep Pap results are abnormal, a pathologist will review the case at an additional charge.
