What is the purpose of exfoliative cytology?
Exfoliative cytology is a non-invasive test that uses the Tzanck smear technique to identify disease by examining the structure of cells obtained from scraped samples..
What is the reason for cytology?

It's mainly used to diagnose or screen for cancer.
It's also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas..
What tests use exfoliative cytology?
Respiratory/exfoliative cytology, which includes bronchial washing, sputum, bronchoalveolar lavage, and bronchial brushing cytology.
Those are commonly used to detect pulmonary infections and malignancies.
Urinary cytology: Urine cytology, bladder washing, and brushing cytology..
Why exfoliative cytology is performed?
Exfoliative cytology is a simple procedure designed to detect the presence of malignancy through analysis of cell structure..
- Its use has thus far been more effective in the diagnosis of cancer of the lung, urinary bladder, esophagus, stomach, rectum and sigmoid colon, and the pleural and peritoneal fluids.
- Specifically, exfoliative cytology performed on oral cancers has high false negative rates, which can exceed 30%.
Furthermore, the effectiveness of exfoliative cytology for detecting dysplasia is even more doubtful, with false negative rates reported as high as 63%.
