Adenosine Deaminase in Peritoneal Fluid
Also known as: ADAPERIT
Use
This test is used to evaluate tuberculous peritonitis. Adenosine Deaminase (ADA) levels in peritoneal fluid can aid in the evaluation of patients suspected of having tuberculous peritonitis. Elevated levels may indicate an inflammatory process, typically associated with tuberculosis.
Special Instructions
Collect the specimen in a leak-proof container. Indicate the source of the fluid on the requisition form to ensure accurate processing and analysis.
Limitations
The test is specifically intended for use with peritoneal fluid; it is unsuitable for whole blood or bronchoalveolar lavage specimens. Turbid specimens are also unacceptable as they may lead to inaccurate results. Stability conditions must be adhered to prevent degradation of the sample, which could lead to misleading results. As this is a laboratory-developed test, it hasn't been FDA cleared or approved, but it is intended for clinical purposes under CLIA regulations.
