Pathology-cytology
Cytology (also known as cytopathology) involves examining cells from bodily tissues or fluids to determine a diagnosis. A certain kind of physician, called a pathologist, Kalpavruksha one Of the Best Pathology hospital in Nagpur. will look at the cells in the tissue sample under a microscope and look for characteristics or abnormalities in the cells. Since cytology only examines cells, which are so tiny, pathologists only need a very small sample of tissue to do a cytology test.
Healthcare providers use cytology in many different areas of medicine, but cytology tests are most commonly used to screen for or diagnose cancer.
What kinds of cytology are there?
There are two main kinds, or branches, of cytology: exfoliative cytology and intervention cytology. Healthcare providers can use cytology tests for almost all areas of your body. Some common types of cytology tests include:
Exfoliative cytology is a branch of cytology in which the cells that a pathologist examines are either “shed” by your body naturally or are manually scraped or brushed (exfoliated) from the surface of your tissue.
Examples of exfoliative cytology that involve manual tissue brushing or scraping include:
Gynecological samples: A Pap smear, which involves brushing off cells from your cervix using a swab, is the most well-known type of exfoliative cytology.
Gastrointestinal tract samples: Your healthcare provider can brush off cells from the lining of your gastrointestinal tract (your stomach and intestines) during an endoscopy procedure for cytology testing.
Skin or mucus samples: Your healthcare provider can scrape off cells from your skin or mucous membranes, such as the inside of your nose or mouth, for cytology testing.
Examples of exfoliative cytology that involve collecting tissues or fluids that your body naturally sheds include:
Respiratory samples: Your provider can collect fluids such as spit and mucus (also called phlegm or sputum) that you cough up for a respiratory cytology test.
Urinary samples: Your provider can collect a urine (pee) sample from you to use for a cytology test.
Discharge or secretion samples: If you experience abnormal bodily discharge, such as from your eye, vagina or nipple, your healthcare provider may collect a sample of the discharge for a cytology test.
