Liquid Based Cytology is the evolution of the conventional Pap Smear Test – a method used since 1943 for screening and tracking of cervical cancer.

The liquid based method is a technique developed in the 1990s, which enables greater precision in the cervical-vaginal oncotic cytopathological diagnosis, as it offers the pathologist a slide with a cleaner background, free of artifacts and with a thin layer of cells. The advantage of the liquid-based cytology is its greater sensitivity, related to the high cell representativeness made possible by the preparation in the liquid medium. There is a clear reduction in unsatisfactory cytology and in the rates of false-negative results. The improvement in slide quality also brings an increase in laboratory productivity.
