The Adenosine Deaminase (ADA) lab test measures the levels of the ADA enzyme in body fluids, particularly pleural fluid, to help diagnose and monitor conditions like tuberculosis (TB). Elevated ADA levels in pleural fluid often indicate TB infection in the lungs, while elevated levels in other fluids like cerebrospinal fluid can point to other infections or immune-related issues. Here's a more detailed explanation: What is ADA? ADA is an enzyme involved in purine metabolism, a process that helps break down adenosine, a molecule essential for cell function. Why is it tested? The ADA test is mainly used to help diagnose TB, especially when fluid is present around the lungs (pleural effusion). How is the sample collected? For pleural fluid analysis, a needle is inserted into the chest cavity to collect fluid. Other fluids like cerebrospinal fluid can be collected via lumbar puncture. What do the results mean? Elevated ADA levels in pleural fluid are often associated with TB, while elevated levels in other fluids can indicate various infections or immune-related conditions. Other uses: The ADA test can also be used to assess the activity of the immune system and can be helpful in diagnosing certain immunodeficiency disorders. In summary, the ADA lab test is a valuable tool for diagnosing and monitoring TB and other conditions by measuring ADA enzyme levels in body fluids, particularly pleural fluid, .
