Alkaline Phosphatase (ALP)
is found in many different tissues and organs, including liver, bone,
intestine, placenta, kidneys, lungs and red blood cells. Isoenzymes of
the liver alkaline phosphatase and bone alkaline phosphatase fractions
account for 80% of the activity found in normal blood. This activity
increases in both liver disease and bone disease, hence ALP is most
commonly utilized in diagnostic tests for these diseases.
