Adenosine Deaminase in Pericardial Fluid
Also known as: ADAPERCAR
Use
The Adenosine Deaminase in Pericardial Fluid test is utilized to evaluate the presence of tuberculous pericarditis. This condition may cause elevated levels of adenosine deaminase in the pericardial fluid, and measuring these levels can aid in the diagnostic process. The test results can contribute to understanding the disease state and guiding appropriate treatment courses, particularly in regions where tuberculosis is prevalent.
Special Instructions
Not provided.
Limitations
The test has not been cleared or approved by the US Food and Drug Administration, indicating its usage as a Laboratory Developed Test (LDT). Accuracy of the test depends on proper handling and processing of the specimen. It is critically important to avoid using whole blood or bronchoalveolar lavage specimens, as these are unacceptable for this assay. Turbid samples may also result in unreliable results and should be rejected. The quantitative spectrophotometry method employed may have limitations in extremely low or high concentration ranges of adenosine deaminase.
