According to MedlinePlus, the normal level for serum lipase is between 0 and 160 U/L, and the normal level for serum amylase is 40 to 140 U/L. The Medical University of South Carolina notes that the test results depend on various factors, including age, gender and the test method used.
MedlinePlus explains that both enzymes are produced by the pancreas. Amylase breaks down carbohydrates into simple sugars, and lipase is crucial for digesting fats into fatty acids.
Elevated level of both enzymes at the same time is a symptom of pancreatitis, according to the Medical University of South Carolina, but there are many prescription drugs and some over-the-counter drugs that also increase the levels of both amylase and lipase.
