What does a cytology test look for?

Can cytology detect cancer?

Some cytology tests, such as the Pap test, are mainly used for screening, while others can accurately identify cancers (see “Scrape or brush cytology” below). When cytology results show cancer, often a biopsy is also done to be sure before treatment is started.

What is the most common test done in cytology?

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.

How accurate is a urine cytology test?

Urine cytology is associated with a significant false-negative rate, especially for low-grade carcinoma (10-50% accuracy rate). The false-positive rate is 1-12%, although cytology has a 95% accuracy rate for diagnosing high-grade carcinoma and CIS. Urine cytology is often the test used for diagnosis of CIS.

What is the most common cytology test and how is it collected?

The most common type of intervention cytology is fine-needle aspiration (FNA). A healthcare provider will inject a thin needle into the area that they need to sample and draw out fluid. A pathologist then examines the cells in the fluid under a microscope.

Biopsy. During a biopsy, your doctor collects a sample of cells for testing in the laboratory.

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 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.

Can a urine test detect leukemia?

Leukemic cells in urine can be diagnosed readily by cytological examination in cases where more invasive procedures are difficult to perform. Additionally, cell block sections can be utilized to determine the immunocytochemical profile of the tumor cells to confirm the diagnosis.
