Cytology Exam of Pleural Fluid

Alternate Names : Pleural Fluid Cytology

Pleural fluid is the fluid that surrounds the lungs and lubricates their linings. This test can help identify any cancer cells if they are present in the pleural fluid.

Who is a candidate for the test?

This test is commonly performed when an abnormally increased amount of pleural fluid is present. It can help determine if cancer is the cause of the increased fluid.

How is the test performed?

In this test, the skin over an area of the lungs is cleaned with an antiseptic. The area is then numbed with a local numbing medicine. After the skin is numb, a thin needle is passed through the skin and into the space surrounding the lungs. A small volume of fluid is taken out. The fluid is sent to the laboratory. A microscope is then used to examine any cells that are in the fluid.
