Gynecologic Pap Test (Image-guided), Liquid-based Preparation and Chlamydia/Gonococcus and Herpes Simplex Virus (HSV) Types 1 and 2, NAA

Test Number 198310
Test number copied
CPT 87491; 87529(x2); 87591; 88175

Test Details

Methodology

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

Result Turnaround Time

4 - 8 days

Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Genital Herpes Diagnosis: Technology and Test Options

Microbiology Specimen Collection and Transport Guide

Use

Diagnose primary or metastatic neoplasm; detect Chlamydia trachomatis and Neisseria gonorrhoeae; detect and type active HSV shedding.

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 smears 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.)

HSV NAA is a single test that both detects the presence of HSV DNA and determines which type is present in the positive samples. There is no mechanism, therefore, for testing for HSV-1 without simultaneously testing for HSV-2.

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.

Testing for Chlamydia trachomatis and Neisseria gonorrhoeae 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 and Neisseria gonorrhoeae testing.

Any time a transport device used for molecular testing is processed, the chance of cross-specimen contamination increases. Aptima® transports can be placed directly on the analyzer, limiting the possibility of cross- specimen contamination.

This test is intended for use as an aid in the diagnosis of herpes simplex virus (HSV) infections with active viral shedding; it also differentiates HSV-1 from HSV-2. Negative HSV NAA results indicate lack of viral shedding but do not confirm absence of previous infection.

Specimen Requirements

Specimen

Cervical cells collected by one of the methods described below.

Volume

ThinPrep® vial or ThinPrep® vial with optional additional Aptima® swab collection kit (for Chlamydia/Gonococcus).

Minimum Volume

A minimum volume cannot be determined for the ThinPrep® vial because it varies depending on the cellularity of the specimen. Specimens collected with the Gen-Probe® Aptima® swab collection kit must arrive intact.

Container

ThinPrep® vial or ThinPrep® vial and Aptima® swab collection kit (for Chlamydia/Gonococcus)

Collection Instructions

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 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 and Gonococcus: Use the Gen-Probe® Aptima® swab collection kit. (Note: Do not use the Gen-Probe® PACE DNA probe 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 performed within 21 days of collection. Liquid-based cytology specimens must be tested within seven days for Chlamydia/Gonococcus and HSV; 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 patients; 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 Chlamydia trachomatis and Neisseria gonorrhoeae: 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 blue-shafted collection swab. For HSV: liquid-based cytology specimen more than seven days old.
