The increase of serum amylase can be measured within 24 hours after the onset of the disease, and the serum amylase value is obviously increased by >: 500U/dl (normal value is 40 ~ 180 u/dl, Somoggi method), and then gradually decreases to normal within 7 days. Determination of urinary amylase is also a sensitive index for diagnosis of this disease. Urinary amylase increased slightly at night, but the duration was longer than that of serum amylase. Urinary amylase is obviously increased (normal value is 80-300U/dl, Somoggi method), which has diagnostic significance. (Excerpted from Encyclopedia)

Gastroenteritis can increase blood amylase, but it is only meaningful to increase it by three times. You may go to the emergency department too early, and the amylase has not risen yet, so the later review is higher than before. Judging from your blood amylase value, pancreatitis is basically ruled out. You can also look at the symptoms. Pancreatitis has severe abdominal pain, which is different from gastroenteritis. Pain mostly radiates to the back, and generally vomiting is very severe. If you are not at ease, you need further inspection.
