| Clinical Use | Adenosine deaminase (ADA) is an endogenous tissue enzyme which is released into the serum in patients with many different types of malignancies and infections, including viral hepatitis, infectious mononucleosis, typhoid fever, and tuberculosis. It is the most useful single test in portal hypertension (ascites) associated with liver cirrhosis. In pleural fluid, elevated ADA levels are very commonly associated with tuberculosis, although increased ADA activity may be found in effusions due to a number of causes, including TB, bacterial infections, rheumatologic disease, and lymphoproliferative disorders. In CSF, ADA is elevated in cases of tuberculous meningitis. |
