Test Details

Use

Diagnose primary or metastatic neoplasm. Detect and type active HSV shedding. The high-risk HPV test is used for types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68, without differentiation of the individual type. This assay aids in the diagnosis of sexually-transmitted HPV infection and in the triage of patients with an ASCUS Pap smear result.

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 13 most common high-risk HPV types and cannot determine the specific HPV type present.

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.

Methodology

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

Specimen Requirements

Specimen

Cervical cells collected by one of the methods described below.

Volume

ThinPrep® vial or SurePath™ vial

Minimum Volume

A minimum volume cannot be determined for the ThinPrep® vial because it varies depending on the cellularity of the specimen. The entire SurePath™ specimen should arrive intact.

Container

ThinPrep® vial or SurePath™ vial

Patient Preparation

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

Collection

ThinPrep® Vial−Broom Only:

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.

SurePath™ Vial: When using the SurePath™ vial, the cervical broom must be used for specimen collection. Insert the broom into the cervical os and rotate five times. Place the broom head into the CytoRich™ preservative fluid in the SurePath™ collection vial. Tightly cap the vial.

Storage Instructions

Maintain liquid-based cytology specimens at room temperature. Pap processing must be performed within 21 days of collection. SurePath™ vial must be processed for testing within 21 days of collection for HPV. Specimens in ThinPrep® vials must be processed for testing within three months of collection for HPV. Liquid-based cytology specimens must be tested within seven days for HSV.

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 manufacturer's label; frozen specimen. For Pap: liquid-based cytology specimen more than 21 days old. For HPV: specimen more than 21 days old in SurePath™ liquid-based preservative; specimen more than three months old in ThinPrep® vial. For HSV: liquid-based cytology specimen more than seven days old.

Clinical Information

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.)

If ThinPrep® vials are QNS for the hybrid capture assay, then a test requiring a lower input volume will be automatically performed if there is sufficient volume to perform that assay.

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.
