ADA, Ascitic fluid

Description

This test measures the level of adenosine deaminase (ADA) in ascitic fluid, which is excess fluid in the abdominal cavity. It’s primarily used to diagnose tuberculous peritonitis, a form of extrapulmonary tuberculosis affecting the peritoneum. Elevated ADA levels in ascitic fluid can strongly indicate tuberculosis infection. The test helps differentiate between tuberculosis and other causes of ascites, such as malignancy or liver disease. It’s particularly useful in areas with high tuberculosis prevalence or when other diagnostic methods are inconclusive.
