A cytology examination of pleural fluid detects the presence of cancerous (malignant) cells. The pleural space surrounds the lungs and normally contains only enough fluid to lubricate the lining of the lung (pleura).
Alternative Names:
Pleural fluid cytology
How the test is performed:
The test is performed by inserting a needle into the pleural space to draw off a sample of pleural fluid (the procedure is called thoracentesis). The sample of fluid is examined under the microscope for the presence of abnormal cells.
How to prepare for the test:
Food or fluid is not restricted. Do not move, cough, or breathe deeply during the test.
How the test will feel:
The skin is cleansed, and shaved if necessary, around the insertion site. Local anesthetic to numb the site may be injected into the skin. You may feel pressure or a sticking sensation as the needle enters the skin and pleural space. Inform the health care provider if you develop shortness of breath after the test.
