Alkaline phosphatase (ALP)

Alkaline phosphatase (ALP) is an enzyme found mostly in the liver, bones, kidneys, and bile ducts. It plays a key role in breaking down proteins and building up bones. When blood tests show abnormal ALP levels, it can indicate issues like liver disease, bone disorders, or blockages in the bile ducts. Doctors often measure ALP to help diagnose or monitor these conditions. Elevated or decreased ALP levels can provide important clues about your overall health, especially relating to liver and bone functions.
