The LAP test is a measure of how much level of a protein called Alkaline phosphatase which is found in the WBCs (white blood cells) of the body is present.
Alkaline phosphatase is a group of enzymes present throughout the body especially in the liver, kidneys, placenta, bile duct and bone tissues and these enzymes remove phosphate groups from various molecules in the body. So, Leukocyte Alkaline Phosphatase is the one present in leukocytes and its control is related to pituitary-adrenal function. Its value alone is not diagnostic of a particular disease but related to other available clinical data.
The normal range for LAP is 44 – 147 IU/L.
