LYNDHURST, N.J., Nov. 14 /PRNewswire-FirstCall/ -- A pioneer in the science and standardization of cervical disease diagnosis, Ronald D. Luff, M.D., M.P.H, and Director of Anatomic Clinical Trials at Quest Diagnostics (NYSE: DGX), recently received a lifetime achievement honor -- the 2006 Papanicolaou Award -- from the American Society of Cytopathology (ASC) at the group's annual scientific meeting in Toronto.

Presented annually to a physician or Ph.D. recognized by their peers for excellence in research and contributions in the field of cytology, the Papanicolaou Award is the ASC's highest honor and is named for the late Greek- American pathologist and cytologist George N. Papanicolaou, who developed the eponymous test, the Pap smear, for the early detection and treatment of cervical cancer.

Dr. Luff received the 2006 Papanicolaou Award for his innumerable contributions to the field of cytology and cytopathology, most notably for his work as the former Chairman of the Editorial Committee for The Bethesda System. In this role, Dr. Luff was instrumental in establishing the first nationwide system to standardize the terminology used in the diagnosis and prevention of cervical disease.

"I am humbled and grateful for the recognition given to me by my peers," said Dr. Luff. "I have made it my life's work to improve diagnosing procedures, enabling more effective treatment."

"Dr. Luff's contribution to the field of cytology supports Quest Diagnostics' commitment to innovation and progressive science," said Joyce G. Schwartz, M.D., Vice President and Chief Laboratory Officer, Quest Diagnostics. "We are extremely proud that the scientists and physicians of Quest Diagnostics, as this award shows, are recognized as among the best and the brightest in medicine today."
