Papanicolaou stain (also Papanicolaou's stain and Pap stain) is a multichromatic (multicolored) cytological staining technique developed by George Papanicolaou in 1942. [ 1 ] [ 2 ] [ 3 ] The Papanicolaou stain is one of the most widely used stains in cytology , [ 1 ] where it is used to aid pathologists in making a diagnosis.
The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), [1] cervical smear (BE), cervical screening (BE), [2] or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or, more rarely, anus (in both men and women).

During a pap smear, doctors collect a sample of the cells from the cervix to look at under a microscope to examine for any abnormalities or signs of pre-cancerous changes. [17] While many abnormalities on pap smears are not indicative of cervical cancer, [ 14 ] the doctor may recommend additional testing to gain a better understanding of the ...
The task force has introduced a recommendation that women over the age of 30 test for high-risk human papilloma viruses (HPV) every five years rather than relying on pap smears to detect cervical ...
The Pap test can be used as a screening test but produces a false negative in up to 50% of cases of cervical cancer. [ 58 ] [ 59 ] Another concern is the cost of doing Pap tests, which makes them unaffordable in many areas of the world.

Unfortunately, Pap smears alone are not adequate for the diagnosis of SCC; patients may be misdiagnosed with non-SCC on the basis of Pap smear results alone. Imaging studies are necessary for proper diagnosis; it has been proposed that MRI is the highest standard for the imaging evaluation of uterine cervical cancer.
The two screening methods available are the Pap smear and testing for HPV. CIN is usually discovered by a screening test, the Pap smear. The purpose of this test is to detect potentially precancerous changes through random sampling of the transformation zone. Pap smear results may be reported using the Bethesda system (see above).
