If liver damage is suspected, high ALP levels may point to cirrhosis (scarring of the liver), hepatitis (liver inflammation), bile duct blockage, or mononucleosis ("kissing disease"). High levels may also indicate a concern related to the bones such as rickets, Pagets disease, bone cancer, or an overactive parathyroid gland. ALP is also found in the placenta, kidneys .
