1. Do elevated amylase levels always mean that I have a pancreatic condition?
No. Amylase levels may also be significantly increased in people with gallbladder attacks. Urine and blood amylase levels may be moderately elevated with a variety of other conditions, such as ovarian cancer, lung cancer, tubal pregnancy, acute appendicitis, diabetic ketoacidosis, mumps, intestinal obstruction, or perforated ulcer, but amylase tests are not generally used to diagnose or monitor these disorders.
3. What is the difference between P-amylase and S-amylase?
Amylase is an enzyme that has several different forms called isoenzymes. Different tissues make different forms. P-amylase refers to the type of amylase made mainly in the pancreas. S-amylase refers to the type of amylase made mainly by the salivary glands. P-amylase in the blood increases when the pancreas is inflamed or damaged. S-amylase in the blood increases when the salivary gland is inflamed or damaged. Measuring pancreatic amylase, or P-amylase, may be useful in determining if an increase in a total amylase level is due to acute pancreatitis.
