Description: Alkaline phosphatase (ALP) is a substance found in all body tissues. Each type is different and is called an isoenzyme. Its structure depends on where in the body it is produced, such as the liver, bone, kidney, bowel (intestine), and in the placenta of women who are pregnant. When the Total Alkaline Phosphatase activity is increased, the Isoenzymes are useful in determining the source of the increased activity.
