Adenosine Deaminase (ADA) – Body Fluid is a test that measures the activity of the ADA enzyme in fluids such as pleural, peritoneal, cerebrospinal, or other body fluids. It is needed to help investigate the cause of fluid accumulation and may support the evaluation of infections, particularly tuberculosis, depending on the type of fluid and clinical findings. Results are interpreted alongside other laboratory tests and clinical information.
ADA can be measured in several body fluids, including pleural fluid, ascitic or peritoneal fluid, cerebrospinal fluid, and occasionally other fluids, depending on the clinical situation.
An elevated ADA level may support the possibility of tuberculosis, particularly in pleural fluid, but it can also occur with other infections, inflammatory conditions, and some malignancies.
No. ADA is not specific enough to confirm tuberculosis by itself. The result should be interpreted with symptoms, imaging, microbiological tests, and other laboratory findings.
Yes. Tuberculous pleuritis can produce elevated ADA levels in pleural fluid, making the test useful as part of the diagnostic evaluation.
Yes. Elevated ADA may occur with bacterial infections, other inflammatory diseases, certain malignancies, and other conditions depending on the type of body fluid tested.
