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
Alternative NamesPleural fluid cytology
How the test is performedA 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 testThe laboratory test requires no preparation. For information on how to prepare for removal of the fluid sample, see: Thoracentesis
How the test will feelSee: Thoracentesis
Why the test is performedA 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.
Normal ValuesNormal cells are seen.
What abnormal results meanIn an abnormal test, there are cancerous (malignant) cells. This may mean there is a cancerous tumor. This test most often detects:
This test may also be done for cancer that has spread to the lung.
What the risks areThere are no risks involved with a cytology exam.
For information risks related to the procedure to remove a sample of pleural fluid, see: Thoracentesis

What else can I help you with?
What is the thin watery fluid that occurs between the pleural membranes called?
The thin watery fluid that occurs between the pleural membranes is called pleural fluid. This fluid helps to reduce friction between the two layers of the pleura, allowing smooth movement of the lungs during breathing.
What is the fluid located between the pleural membranes?
Pleural Fluid. It is mostly made up of tissue fluidPleural spacePleural fluid
What is a pleural hemorrage?
Pleural fluid is the fluid found in your lungs. My guess is that a pleural hemorrhage would be the result of fluid buildup expanding the lungs to the point where the tiny sacs in your lungs could rupture.
When is a pleural biopsy needed?
A pleural biopsy is needed when there is suspicion of underlying pleural disease or cancer that is causing symptoms such as unexplained fluid buildup in the pleural space, persistent chest pain, or unexplained fluid in the lungs. It is usually performed when other less invasive tests, such as imaging or fluid analysis, do not provide a definitive diagnosis.
Is ascites a condition in which fluid collects in the pleural cavity?
No, ascites is a condition in which fluid collects in the abdominal cavity.
How is Pleural fluid contained?
Pleural fluid is contained within the pleural space, a thin fluid-filled cavity between the two layers of the pleura (lining of the lungs and chest cavity). This space prevents the fluid from leaking into surrounding tissues. The balance between fluid production and absorption by the pleura helps maintain the fluid in this contained space.
What is the specific fluid in the pleural cavity?
The specific fluid in the pleural cavity is called pleural fluid. It acts as a lubricant, reducing friction between the two layers of the pleura (membranes surrounding the lungs), allowing for smooth breathing movements.
What The is the thin fluid-filled space also known as the pleural space?
this answer is pleural cavity
Plural fluid functions- respiration?
Pleural fluid is present in the pleural sac. This fluid act as a lubricant and minimizes the friction between outer and inner layer of pleura, during respiration.
How is a Denver Catheter drained?
Pleural drain that patient can drain fluid from pleural effusion or ascites on own.
What do the pleural cavities contain?
Pleural cavity is the potential space. There is no gap between the outer and the inner pleura. There is very little fluid in the pleural cavity. You have negative pressure in the pleural cavity.
Is the excess accumulation of fluid in the pleural space which keeps the lung from fully expanding?
Pleural effusion: is the excess acumulation of fluid in the pleural space. This produces a feeling of breatlessness because it prevetns the lung from fully expanding. Effusion is the escape of fluid from blood or lymphatic vessels into the tissues or into a body cavity.
