What is normal amylase?

The normal value of amylase in blood is between 40-110u. Amylase generally comes from pancreas and parotid gland. If amylase is found to be elevated, accompanied by local abdominal pain, it is usually caused by acute pancreatitis. Suggestion: You can go to the digestive department of the local regular hospital for treatment, conduct relevant examinations, and find out the cause.
