There are at least 7 isoenzymes of amylase in human tissue. Salivary and pancreatic forms exist in serum. Amylase activity can be found in extracts from semen, testes, ovaries, fallopian tubes, striated muscle, lung, and adipose tissue. It is also found in colostrums, tears, and milk. An increase of amylase activity may not necessarily be due to pancreatitis. Therefore, determining the organ source is useful by determining whether the major isoenzyme present is type P (pancreatic) or type S (salivary) by amylase isoenzyme determination. Some of the conditions that may lead to elevated total amylase include renal insufficiency (mixed type S and P), neoplastic hyperamylasemia (bronchogenic or ovarian) (S-type), salivary gland lesions (S-type), macroamylasemia (S-type predominantly), perforated peptic ulcer (P-type), intestinal obstruction (P-type), acute appendicitis, diabetic ketoacidosis (mixed S and P-types), acute alcoholism (mixed), ruptured ectopic pregnancy (S-type), and medicinal opiates (P-type) or heroin addiction (S-type). Amylase isoenzymes are useful in differentiating between S-type or P-type amylase.

Avoid hemolysis.
