What is the most common cytology test?
The most common samples in cytology are exfoliative, including cervical smears (Pap smears), urine and sputum. These are usually screened by trained cytotechnicians or, in some laboratories, computerised automated systems, to look for any suspicious cells.
What tests are done in cytology?
Cytopathology Test List
- Anal pap.
- Body cavity fluids, cytopathology.
- Bronchoalveolar lavage.
- Brush biopsy specimen.

- Fine needle aspiration – clinician obtains sample.
- Fine needle aspiration – pathologist obtains sample.
What is the most common cytology test and how is it collected?
A urine cytology test requires a urine sample, which you provide by urinating into a sterile container. In some cases, a urine sample is collected using a thin, hollow tube (catheter) that’s inserted into your urethra and moved up to your bladder.
What are the types of cytology?
There are two methods of collecting cells for cytopathologic analysis: exfoliative cytology, and intervention cytology.
- Exfoliative cytology.
- Intervention cytology.
- Imprint cytology.
What does cytology involve?
Cytology is the exam of a single cell type, as often found in fluid specimens. 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.
How is cytology done?
Scrape or brush cytology: This procedure involves scraping or brushing some cells from the organ or tissue that’s being tested. Some areas where doctors use scrape or brush cytology include the breathing tubes that lead to the lungs, cervix (for a Pap test), esophagus, mouth and stomach.
How long does a cytology test take?
The procedure takes between 10 and 20 minutes. Because the urine from your first morning urination remains in your bladder for many hours through the night, the cells may degrade and not be useful for urine cytology. However, this doesn’t mean you should urinate right before the test.
How accurate are cytology test?
Many studies have evaluated the accuracy of urine cytology in the detection of bladder cancer. Overall, the reported sensitivity ranges from 20% to 97.3%; specificity ranges from 74% to 99.5%.
What is called cytology?
Cytology is the study of individual cells of the body, as opposed to histology which is the study of whole human tissue itself.
What is the difference between cytology and biopsy?
However, the emphasis in cytological examination is on cellular changes. In biopsy, we can study tissue patterns and inter-relationships as well as cellular changes.
What are the most important tools of cytology?
The most famous ones are FNA, fine needle aspiration biopsy (FNAB), and needle aspiration biopsy cytology (NABC). All of them mean the same thing; aspirating cellular material using a fine needle to make a diagnosis.
What is cytology screening?
A cervical cytology test is a test used to detect abnormal or potentially abnormal cells from the uterine cervix (neck of the womb), and to test for infection with Human Papilloma Virus (HPV).
