When these rates are above normal, characterizing a high amylase, also known as hyperamylasemia, this may mean a sign of inflammation, a possible disease in the pancreas or salivary glands. When values ??are below normal, this may indicate a pancreatic insufficiency or even the presence of serious diseases in the liver.
The main causes involved in the high amylase problem are as follows:

Amylase is an enzyme, or special protein, that helps you digest carbohydrates. Most of the amylase in your body is made by your pancreas and salivary glands.
Amylase and lipase tests are used to detect pancreatitis. The tests measure the amount of these enzymes circulating in your bloodstream. These enzymes are typically checked when you have symptoms of acute pancreatitis or another pancreatic disorder and your doctor wants to confirm the diagnosis.
Code E78. 5 is the diagnosis code used for Hyperlipidemia, Unspecified, a disorder of lipoprotein metabolism other lipidemias. It is a condition with excess lipids in the blood.

Other causes of elevated serum amylase are inflammation of salivary glands (mumps), biliary tract disease and bowel obstruction. Elevated serum amylase can also be seen with drugs (e.g., morphine) which constrict the pancreatic duct sphincter preventing excretion of amylase into the intestine.
In acute pancreatitis, serum amylase begins to rise within 6-24 hours, remains elevated for a few days and returns to normal in 3-7 days.

The measure of total amylase includes both α-amylase from the salivary glands and different macro-amylase molecules (Smith, 2005). The pancreas and the salivary glands release different isoenzymes of amylase; these different isoenzymes can be identified using monocolonal antibodies.
Following injury to the pancreas, these enzymes are released into the circulation, along with other enzymes, such as elastase, and trypsin. As each enzyme is cleared from the bloodstream at varying rates, the sensitivity of blood samples measuring enzyme levels is dependent on timing (Shah, 2018).
Because of limitations in sensitivity, specificity, and positive and negative predictive value, serum amylase alone cannot be used reliably for the diagnosis of AP (acute pancreatitis) and serum lipase is preferred. Serum lipase is now the preferred test due to its improved sensitivity for a longer period of time (Shah, 2018).
The measurement of pancreatic amylase enzymes is associated with improved sensitivity and specificity, however pancreatic amylase levels have been “largely disregarded” and laboratories continue to report total amylase levels (Ismail, 2017). Every year in the United States, approximately 275,000 hospital admissions are attributed ...

Serum amylase testing is considered not medically necessary for acute and chronic pancreatitis and all other conditions. The following codes for treatments and procedures applicable to this guideline are included below for informational purposes.
Amylase concentrations may also be normal in alcohol-induced acute pancreatitis (ACG, 2013). In summary, lipase levels are affected by fewer comorbid conditions, and there is no advantage in evaluating both amylase and lipase levels.
