The Bethesda System (TBS) for Pap tests is a classification system
developed by the National Cancer Institute (NCI). This system provides detailed
information about the quality of the cell sample and the types of cell changes
Doctors who take the cell sample and laboratory specialists
(cytologists) who examine the cervical cells use TBS. This system provides a
standardized language for reporting and communicating any changes to cells that
may pose health risks.
