Generally urinary amylase above the upper limit of normal can assist in the diagnosis of pancreatitis, but a diagnosis of pancreatitis cannot be made solely on the basis of a single indicator of high urinary amylase. The normal range of urinary amylase is 100-300 U/L, and the normal reference value varies slightly depending on the test method and reagent. When the patient has pancreatitis, generally the urine amylase will exceed the upper limit of normal value, but due to the many interfering factors, the urine amylase level is only used as a reference for diagnosing pancreatitis. Clinical diagnosis of pancreatitis is usually evaluated by comprehensive diagnostic results. Usually, the clinical manifestations of pancreatitis patients include epigastric pain, nausea and vomiting, fever with or without systemic inflammatory response syndrome; blood amylase is more than three times the normal value, which can be used as one of the diagnostic criteria; and enhanced CT suggests pancreatic imaging changes during imaging examination, which also has diagnostic value. It is recommended that patients with high urinary amylase should seek further medical treatment, improve relevant examinations, clarify the cause of the disease and standardize the treatment.
