The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Design Description The study was designed to have the 295 pairs (590 individual slides) of slides. Each subject was represented by a pair of slides: a Pap Smear slide and a MonoPrep Pap test slide. The MonoPrep Pap test slide was prepared from the Pap Smear slide residuum. Both sets of slides were assessed for specimen adequacy by the participating laboratories, and the slides were labeled as 'satisfactory' or 'unsatisfactory' accordingly. The adequacy determination (satisfactory/unsatisfactory status) and the underlying reason for an unsatisfactory status according to the TBS2001 criteria. For slides with adequacy determination of satisfactory, a diagnosis was assigned to the slide according to the TBS2001 criteria.
Study Population Description Study Poluation: Women 18 years or older who receive cervical cancer screening. Indication: The MonoGen Pap Test is intended for use in collecting and preparing cervical-vaginal cytology specimens for Pap stain-based screening for cervical cancer, its precursor lesions, and other cytologic categories and conditions defined by the 2001 Bethesda System for Reporting Results of Cervical Cytology.
Sample Size 295 patients, 85 sites
Data Collection The goal of the study was to evaluate cytology slides for adequacy determination and the underlying reason for unsatisfactory status. Data collection consisted of obtaining cervical cytology specimens.
Follow-up Visits and Length of Follow-up Follow-up was not required for this study.
