What it is
Alkaline phosphatase is one substance measured in liver function testing.[1]
Why it matters
In liver context, ALP is often read with bilirubin and other panel components when bile-flow questions arise.[1]
What it affects
- ALP also appears in bone contexts, so the clinical source of a change matters.[1]
Interpretation traps
- Do not treat ALP as a liver-only marker.[1]
