What is a cytological assessment?

Cytologic evaluation is the analysis of cells from the body under a microscope. This is done to determine what the cells look like, and how they form and function. The test is usually used to look for cancers and precancerous changes. It may also be used to look for viral infections in cells.

What is cytological technique?

Cytological techniques are methods used in the study or manipulation of cells. These include methods used in cell biology to culture, track, phenotype, sort and screen cells in populations or tissues, and molecular methods to understand cellular function.

What are cytological samples?

Body fluid cytology: Common samples include pleural fluid, pericardial fluid, peritoneal fluid, and cerebrospinal fluid (CSF) cytology. Similar to respiratory samples, those are also used mainly to detect malignancies and infections.

What is procedure for cytology test?

What is a simple definition of cytology?

Definition of cytology 1a : a branch of biology dealing with the structure, function, multiplication, pathology, and life history of cells : cell biology. b : the cellular aspects of a phenomenon, process, or structure liver cytology.

How do you perform a cytology test?

What is cytological smear?

In cytological smear, the sample is either smeared on a glass slide or made on a monolaye, and it is subsequently stained with the following stains- Papanicolaou, Diff quick and heamatoxylin and eosin. Samples of CB are fixed in 10% neutral buffered formalin and then treated as a tissue block.

How reliable are cytology tests?

The accuracy of urine cytology depends on several factors that are mainly related to tumor grade, the nature of specimen, and sampling. It has long been known that urine cytology is accurate in the diagnosis of high-grade urothelial carcinoma (HGUCA) with cytohistologic correlation reported as high as 98%.
