CSF, Adenosine deaminase (ADA) is a protein produced by body cells and is associated with lymphocyte activation. This test measures the amount of adenosine deaminase in pleural fluid. Elevated ADA levels indicate tuberculosis infection of the pleurae. It also helps to determine infections in other fluids such as peritoneal fluid or cerebrospinal fluid (CSF).

A: The ADA CSF test specifically measures ADA levels in the cerebrospinal fluid, focusing on conditions affecting the central nervous system.

Q3: What other conditions can affect ADA levels in CSF?

A: Conditions such as viral infections, autoimmune disorders, and other central nervous system infections can also impact ADA levels in CSF.

Q4: Is the ADA CSF test painful?

A: The lumbar puncture procedure for collecting CSF may cause some discomfort, but it is generally a safe and routine procedure.

Q5: How long does it take to get the ADA CSF test results?

A: The test results are usually available within a few hours to a day after the CSF sample is collected and sent to the laboratory for analysis.
