What is Alkaline Phosphatase Test?
An ALP test is used to determine the levels of Alkaline phosphatase in blood. The alkaline phosphatase is an enzyme mostly present in the liver, kidneys, digestive system, and bones. ALP is also present in the placenta of pregnant women. The bones and liver are primary sources of alkaline phosphatase enzyme in the blood. Thus, increased levels of alkaline phosphatase in the blood indicate liver or bone damage. An ALP test could be an ALP isoenzyme or an ALP general test. Sometimes this test is also included as a part of a routine hepatic or liver panel test. These are a group of tests that are used to determine how well your liver is functioning. The ALP general test will measure the concentration of total ALP present in the blood. But, an ALP isoenzyme test can help distinguish between the different forms of ALPs in the blood and tell the source of the enzyme.
