A Pap smear is a screening test for cervical cancer. The results are typically categorized as normal, abnormal, or unsatisfactory. Abnormal results may indicate the presence of atypical cells, which could range from low-grade squamous intraepithelial lesions (LSIL) to high-grade squamous intraepithelial lesions (HSIL). Further testing, such as a colposcopy, may be needed for abnormal results.
