Test Background ALP is typically ubiquitous but predominates in the liver, bile ducts, bone and intestinal tissues. Leakage into the vasculature correlates with increased ALP turnover secondary to organ/tissue damage or increased production as a consequence of growth cycles, pregnancy or metastasis.
Clinical Indications Bone pain, suspected liver impairment Differential diagnosis: liver vs. bone causes (see ALP isoenzymes) consider also GGT
