The ThinPrep Difference

FDA-Approved/Cleared and Chosen by Physicians

The ThinPrep Pap Test is the most comprehensive, FDA-approved, liquid-based pap test available. It offers increased HSIL detection,1 and is the only pap test approved/cleared by the FDA for HPV, Chlamydia/Gonorrhea and Trichomonas testing "out of the vial". Additionally, it is the only pap test for which the FDA has approved labeling supported by multiple peer-reviewed publications2-7 reporting improved glandular disease detection.

The significance of FDA aprrovals/clearance

To obtain FDA approval/clearance, manufacturers must meet rigorous testing criteria demonstrating that their product is safe and effective.8 The criteria require valid scientific evidence to ensure consistent and reproducible product performance, such that the particular requirements for the specific intended use can be fulfilled consistently. The ThinPrep Pap Test met these criteria so that physicians, lab personnel, and patients can be confident using the ThinPrep Pap Test specimen for such tests. In fact, governing bodies such as the American Society for Colposcopy and Cervical Pathology noted that:

"The appropriate use of [ASCCP] guidelines require that laboratories utilize only HPV tests that have been analytically and clinically validated with proven, acceptable reproducibility, clinical sensitivity, specificity, and positive and negative predictive values for cervical cancer and verified precancer (CIN 2,3) as documented by the Food and Drug Administration (FDA) approval and/or publication in peer-reviewed scientific literature."
