Cytology Proficiency Improvement Act of 2006 - Amends the Public Health Service Act to require the Secretary of Health and Human Services to revise national quality assurance standards to assure consistent performance by laboratories of valid and reliable cytology services, to include requirements that each clinical laboratory: (1) ensure that all individuals involved in screening and interpreting cytological preparations participate annually in an approved continuing medical education program in gynecologic cytology that provides each participant with gynecologic cytologic preparations designed to improve locator, recognition, and interpretive skills; and (2) maintain a record of program results.
Requires the Secretary to terminate individual proficiency testing that was in effect before enactment of this Act.
