The 24-hour urine amylase test is employed to identify pancreatic abnormalities. It assesses the levels of amylase, an enzyme produced by the pancreas and salivary glands. Healthcare providers utilize this diagnostic tool to identify conditions such as pancreatitis, hyperamylasemia, or pancreas transplantation. Additionally, the amylase creatinine clearance ratio (ACCR), employed in pancreatitis cases, also relies on urinary amylase levels.
