Amylase

Alpha-Amylase Test

Test Overview

An amylase test measures the amount of this enzyme in a sample of blood taken from a vein or in a sample of urine.

Normally, only low levels of amylase are found in the blood or urine. But if the pancreas or salivary glands become damaged or blocked, more amylase is usually released into the blood and urine. In the blood, amylase levels rise for only a short time. In the urine, amylase may remain high for several days.
