Urinary amylase (UAMY)

Under normal circumstances, a small amount of amylase can be absorbed into the blood and discharged with the urine. Determination of urinary amylase contributes to the diagnosis of pancreatic disease. Urinary amylase is higher than serum amylase, and it can be increased from 12 to 24 hours after onset of acute pancreatitis, and the decline is slower (more than 3 to 10 days). In the acute onset of chronic pancreatitis, there may be a moderate increase. In addition, pancreatic cancer, pancreatic injury, acute cholecystitis, etc., the enzyme activity is also increased. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Severe hepatitis, cirrhosis, diabetes, severe burns, etc. Normal value: Urine amylase (iodine-starch colorimetric method): 100-12000U/L Urine amylase (p-nitrobenzene malt: 120-1200U/L Above normal: Acute pancreatitis and any cause of pancreatic duct obstruction (such as pancreatic cancer, pancreatic injury), acute cholecystitis, gastric ulcer perforation, alcoholism, mumps and so on. negative: Positive: Tips: Do not exercise vigorously, heavy physical labor, stop taking diuretics, amphotericin B and other drugs. Normal value (1) iodine-starch colorimetric method 1000~12000U/L; (2) p-nitrobenzene malt heptasaccharide method 120 ~ 1200U / L. Clinical significance Reduced in severe hepatitis, cirrhosis, diabetes, severe burns, etc. Elevated in acute pancreatitis and any cause of pancreatic duct obstruction (such as pancreatic cancer, pancreatic injury), acute cholecystitis, gastric ulcer perforation, alcoholism, mumps and so on. Low results may be diseases: acute cholecystitis, high results of acute pancreatitis may be diseases: diabetes, cirrhosis considerations Before the test: prohibit strenuous exercise, heavy physical labor, stop taking diuretics, amphotericin B and other drugs. Inspection process The urine of the subject was collected and detected by immunological methods. Not suitable for the crowd Generally not. Adverse reactions and risks No.
