Diagnosing acute pancreatitis begins with a thorough medical history and a physical examination of the patient. Subsequently, blood tests are conducted to assess pancreatic, liver, and kidney functions. Imaging studies such as Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI) are performed. To determine if there is inflammation or blockages in the pancreatic duct or bile duct, an endoscopic ultrasound may be considered. A definitive diagnosis of acute pancreatitis is made based on the comprehensive evaluation of all these findings.
