The normal range for a blood amylase test is 25 to 125 units per liter, or 0.4 to 2.1 microkatals per liter, for adults age 60 and younger, according to WebMD. For adults older than 60, normal amylase levels are 24 to 151 units, or 0.4 to 2.5 microkatals per liter.
Amylase is an enzyme produced by the pancreas and salivary glands, explains MedlinePlus. An amylase test measures the amount of the amylase enzyme in the blood, notes WebMD, and involves testing a blood or urine sample. Doctors conduct an amylase test to diagnose and treat pancreatitis and pancreatic diseases and monitor salivary gland inflammation and swelling.
