What is the name of the test, also known as a Pap test, that classifies abnormal cells from the vagina or cervix?

The Papanicolaou test, commonly referred to as a Pap test, is specifically designed to screen for cervical cancer and to detect abnormal cell changes in the cervix and vagina. This test is named after Dr. George Papanicolaou, who developed it in the 1940s. During the procedure, cells are collected from the cervix and examined microscopically to identify any abnormalities that could indicate the presence of precancerous conditions or cancer itself.

This test plays a crucial role in early detection and prevention of cervical cancer, significantly contributing to women's health screening practices. Other tests mentioned, such as a biopsy, are different in that a biopsy involves taking a tissue sample for further examination, while colposcopy is a procedure used to closely examine the cervix using a special instrument after abnormal results from a Pap test. The HPV test detects the presence of the human papillomavirus, which is linked to cervical cancer but is a separate screening method from the Pap test.
