What does Adenosine Deaminase (ADA)-PF measure?
The Adenosine Deaminase (ADA)-PF test measures ADA enzyme activity in pleural fluid. Increased ADA levels may be associated with inflammation or immune-cell activity within the pleural space. Healthcare professionals may use this test as part of the evaluation of pleural effusion, including when tuberculosis or other inflammatory conditions are being considered. Results are interpreted along with symptoms, imaging findings, and other laboratory tests.
