Final answer:
Elevated serum amylase indicates an abnormal increase in pancreatic amylase levels in the bloodstream. It can be indicative of conditions like pancreatitis, parotitis, intestinal obstruction, and diabetes.
Step-by-step explanation:
Elevated serum amylase indicates an abnormal increase in the levels of the pancreatic amylase enzyme in the bloodstream. The pancreas secretes amylase to aid in the digestion of carbohydrates in the small intestine. Elevated levels of serum amylase can be indicative of conditions such as pancreatitis, parotitis, intestinal obstruction, and diabetes. It is important to note that elevated serum amylase is not specific to the liver and can also be found in red blood cells and cardiac and skeletal muscles.
