In extra-pulmonary disease, tubercular samples 33/36 of ascitic fluid, 18/21 of synovial fluid and 48/54 of CSF had ADA levels above the cutoff, while in non-tubercular samples 72/72 of ascitic fluid, 6/9 of synovial fluid and 63/66 of CSF had values below the cutoff (Table 5). Here, ADA is linked to lung disorder.
