Gynecologic Pap Test–Age-based Guideline for Cervical Cancer Screening (Cobas® method) and STDs
Use
Diagnose primary or metastatic neoplasm. Detect Chlamydia trachomatis and Neisseria gonorrhoeae. High-risk HPV is used for types 16 and 18 and a combined result for types 31,33,35,39,45,51,52,56,58,59,66, and 68, without differentiation of the individual type. This information, together with the physician's assessment of cytology history, other risk factors, and professional guidelines, may be used to guide patient management. The results of this test are not intended to prevent women from proceeding to colposcopy.
Special Instructions
Not provided.
Limitations
The test may fail to evaluate properly if there is inadequate cell population from ectocervical, endocervical, or vaginal regions. Lubricating jelly on the vaginal speculum can interfere with the cytologic examination. The specimen volume from liquid-based cytology may limit Pap reprocessing or HPV testing. Negative results do not rule out HPV infection due to potential low levels of infection or sampling errors causing false-negative results. Testing requires special procedures for Chlamydia trachomatis and Neisseria gonorrhoeae, thus can't be added after submission.
