The document discusses the Pap smear test, which screens for cervical cancer. It describes the test procedure, which involves collecting cell samples from the cervix using an Ayres spatula or endocervical brush. The samples are analyzed under a microscope to detect any abnormal or infected cells. Abnormal results are categorized according to the Bethesda system and can range from atypical squamous cells to high-grade lesions and carcinoma. The goal of the Pap smear is to detect cervical changes at early, precancerous stages to prevent cancer from developing.
