Introduction
Pancreatitis is a serious pancreatic disorder, typically diagnosed by measuring serum amylase levels. The optimal time to test blood amylase is more than 2 hours after symptom onset, preferably within 12 hours. It is recommended to seek medical attention as early as possible for amylase testing to confirm the diagnosis and initiate targeted treatment based on test results, thereby preventing disease progression.

Pancreatitis is a serious pancreatic disorder, typically diagnosed by measuring serum amylase levels. The optimal time to test blood amylase is more than 2 hours after symptom onset, preferably within 12 hours.

During acute pancreatitis, blood amylase levels usually begin to rise gradually about 2 hours after the onset of abdominal pain, reaching peak levels around 12 hours after pain starts. The levels then gradually decline after 48 hours and remain elevated for 3–5 days. Therefore, the best window for testing blood amylase in suspected pancreatitis is between 2 and 12 hours after symptom onset. A diagnosis can be confirmed when blood amylase levels are three times higher than normal, accompanied by typical abdominal pain symptoms, and supported by imaging tests such as pancreatic CT or upper abdominal CT.

If pancreatitis is suspected, it is recommended to seek medical attention promptly for blood amylase testing to confirm the diagnosis and initiate targeted treatment based on test results, thereby preventing disease progression.
