Clinical Significance
An elevated level of adenosine deaminase (AD) in human serum, plasma or select body fluids is used as a surrogate marker for inflammation or infectious disease. In CSF, pleural effusions, and pericardial fluid in particular, elevated AD activity has been shown to be associated with tubercular lesions. Additional disease states that may result in elevated AD activity include liver cirrhosis, liver fibrosis, certain malignancies (e. g. lymphoma), viral hepatitis, and autoimmune diseases (e. g. SLE,  rheumatoid arthritis).
