About this biomarker
Alkaline phosphatase, often called ALP, is an enzyme found in the liver, bile ducts, and bone. It is interpreted with other tests to help locate the likely source.
Why it matters
It helps evaluate bile flow patterns and can also reflect bone turnover.
What lower levels may suggest
Low ALP may be seen with malnutrition, some mineral deficiencies, or rare inherited conditions.
What higher levels may suggest
High ALP may be seen with bile duct problems, liver conditions, increased bone turnover, or growth in children and teens.
Common tests
Comprehensive metabolic panel, hepatic function panel, alkaline phosphatase isoenzymes
