Pleural Fluid Culture

A pleural fluid culture is a test to determine the cause of inflammation and excess fluid associated with pleurisy and pleural effusion. It is often performed in conjunction with thoracentesis.

A needle is inserted between your ribs to get a sample of the fluid between your lungs and chest wall. It is then tested in a laboratory for bacterial, viral and fungal infections, as well as for cancer.
