Alkaline Phosphatase (ALP)
What It Is
ALP is an enzyme found in the liver, bones, kidneys, and digestive system. It plays a role in breaking down proteins.
Why It Matters
Elevated ALP can point to liver or bone conditions, making it a useful marker in a comprehensive health screen.
If Levels Are High
High ALP may suggest bile duct obstruction, liver disease, or bone disorders such as Paget's disease.
If Levels Are Low
Low ALP is uncommon but may relate to nutritional deficiencies such as zinc or magnesium.
Preparation
Fasting for 10–12 hours may be recommended for accurate results.
How Often to Test
Annually as part of a liver function panel.
