Cytology exam of pleural fluid
Alternate Names : Pleural fluid cytology
Definition
A cytology examination of pleural fluid is a laboratory test to detect cancerous cells in the pleural space, the area that surrounds the lungs. See: Cytologic evaluation
Why is the Test Performed?
A cytology exam is often used to look for cancers and precancerous changes. Your doctor may order a cytology examination of pleural fluid if you have signs of cancer, or to find the cause of fluid buildup in the pleural space, a condition called pleural effusion.
How is the Test Performed?
A sample of fluid from the pleural space is needed. For information on how the sample is obtained, see: Thoracentesis.
The fluid sample is sent to a laboratory where it is examined under the microscope to determine what the cells look like, and whether they are abnormal. "Cytology" refers to the study of cells.
How to Prepare for the Test?
The laboratory test requires no preparation. For information on how to prepare for removal of the fluid sample, see: Thoracentesis
How will the Test Feel?
