What is the normal range for Amylase?

The standard teaching reference range for Amylase is 30–110 U/L in conventional units, or 0.5–1.84 µkat/L in SI units. This value is measured in serum.

Common causes of a high Amylase

Acute pancreatitis
Salivary gland disease
Bowel obstruction or perforation
Renal failure

Below the range

Common causes of a low Amylase

Advanced chronic pancreatitis
Liver failure

Nursing considerations

Rises early in pancreatitis but is less specific than lipase.
