An Alkaline Phosphatase (ALP) test measures the level of this enzyme in your blood. ALP is found primarily in the liver and bones, with smaller amounts in kidneys, intestines, and placenta. Elevated levels can indicate liver or bone problems.
What This Test Measures
Alkaline Phosphatase (ALP):
An enzyme that helps break down proteins. Different forms (isoenzymes) are produced by different tissues, primarily liver and bone. When these tissues are damaged or more active, ALP is released into the blood.
