Serum amylase level tests measure the concentration of amylase in the serum, an enzyme secreted by the pancreas, salivary glands, and other tissues at minimal levels. Elevated amylase levels can indicate pancreatic and salivary gland disorders, as well as issues related to decreased metabolic clearance and macroamylasemia. Healthcare professionals utilize this test to identify acute or chronic pancreatitis, or pseudocysts.
