Test Description: Pleural Fluid Analysis

Pleural Fluid Analysis is a diagnostic test that examines the fluid found in the pleural space, the area between the lungs and the chest wall. This test helps determine the cause of pleural effusion, a condition where excess fluid accumulates in the pleural cavity. The analysis typically includes measurements of protein, glucose, lactate dehydrogenase (LDH), cell count, and microbiological cultures. It is used to diagnose various conditions such as infections (e.g., pneumonia or tuberculosis), cancers, heart failure, and autoimmune diseases. The results provide valuable insights into the underlying cause of pleural effusion.
