Final answer:
Elevated levels of alkaline phosphatase are typically seen in Paget's disease of the bone.
Step-by-step explanation:
Blood levels of the enzyme alkaline phosphatase are typically elevated in people with Paget's disease of the bone. Alkaline phosphatase is an enzyme in the cells lining the biliary ducts of the liver and is also present in bone tissue. The elevated levels of alkaline phosphatase help in diagnosing Paget's disease along with imaging studies like X-rays and bone scans.
