Special Instructions

Include date of birth, Social Security number (or other identification number), previous malignancy, drug therapy, radiation therapy, last menstrual period (LMP), postmenopausal patient (PMP), surgery (including surgical biopsies), exogenous hormones, abnormal vaginal bleeding, abnormal Pap results, IUD, and all other pertinent clinical information on the cytology test request form.

Note: In accordance with criteria established by CLIA, Pap tests will be referred for pathologist review if laboratory personnel suspect:

• Reactive or reparative cellular changes

• Atypical squamous or glandular cells of undetermined significance

• Cells in the premalignant or malignant category

In these cases, LabCorp will charge for the associated service. (Slides that are routinely reviewed by a pathologist for quality control purposes are not included.)


Expected Turnaround Time

3 - 6 days


Specimen Requirements


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


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.

Optional Dedicated Specimen for Chlamydia, Gonococcus, and Trichomonas: Use the Gen-Probe® Aptima® swab collection kit. Clean the cervix using the larger, white-shafted swab supplied in the Gen-Probe® Aptima® swab collection kit and discard. Insert the smaller, blue-shafted swab into the cervix and rotate for 10 to 30 seconds to ensure good sampling. Carefully withdraw the blue-shafted swab, avoiding 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. Break the swab shaft at the scoreline, using care to avoid splashing contents. Recap the swab specimen transport tube tightly.


Storage Instructions

Maintain liquid-based cytology and Aptima® swab transport specimens at room temperature. Pap processing must be done within 21 days of collection. Specimens in ThinPrep® vials must be processed for testing within 21 days of collection for HPV. Liquid-based cytology specimens must be tested within seven days for Chlamydia/Gonococcus/Trichomonas; if the Aptima® swab transport is used, it must be tested within 60 days.


Patient Preparation

Patient should avoid douches 48 to 72 hours prior to examination. Specimen should not be collected during or shortly after menstrual period.


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 a vial that expired according to the manufacturer's label; frozen specimen; SurePath™ vial. For Pap: liquid-based cytology specimen more than 21 days old. For HPV: specimen more than 21 days old in ThinPrep® vial. For Chlamydia, Gonococcus, and Trichomonas vaginalis: liquid-based cytology specimen more than seven days old; Aptima® specimen more than 60 days old; Gen-Probe® Aptima® collection tube with multiple swabs, white-shafted cleaning swab, or any swab other than the collection swab.


Test Details


Use

Diagnose primary or metastatic neoplasm; detect Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis. 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 HPV 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

Failure to obtain adequate ectocervical, endocervical, or vaginal cell population is suboptimal for evaluation. Excessive use of lubricating jelly on the vaginal speculum will interfere with cytologic examination and may lead to unsatisfactory Pap results. The use of the liquid-based cytology specimen for multiple tests may limit the volume available for Pap reprocessing or HPV testing.

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. This test detects only the 14 most common high-risk HPV types. When reflex conditions are met, HPV type 16 and 18,45 testing is performed.

Testing for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis requires special procedures to be used in the processing of the cytology specimen; therefore, testing for these organisms cannot be added on after the specimen has been submitted. The liquid-based cytology specimen must be processed for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis testing.


Methodology

Image-guided liquid-based Pap test; nucleic acid amplification (NAA)
