Which of the following is a diagnostic lab test for a client with pancreatitis?

Rationale: A. A CBC may show leukocytosis but is not diagnostic for pancreatitis. B. AST/ALT may be elevated if biliary obstruction is present, but they are not specific for pancreatitis. C. Blood glucose may rise in pancreatitis due to impaired insulin release, but it is not diagnostic. D. Amylase and lipase levels are the primary diagnostic lab tests for acute pancreatitis, with lipase being more specific and remaining elevated longer.
