Pap test (redirected from Pap tests)

Pap test, Pap smear, or Papanicolaou test (păp'ənē`kəlou), medical procedure used to detect cancer of the uterine cervix. A scraping, brushing, or smear, is taken from the surface of the vagina or cervix and is prepared on a slide and stained for microscopic examination and cytological analysis. The appearance of the cells determines whether they are normal, suspicious, or cancerous. Although the test is 80% to 95% reliable, results termed suspicious may indicate infection or some abnormal condition other than cancer. The smear technique is also used to detect cancer of other tissues, e.g., in the bladder. The Pap test was developed by G. N. Papanicolaou and H. F. Traut in 1943.
