When to Seek Prompt Care

If you have symptoms like severe abdominal pain, yellow skin or eyes (jaundice), dark urine, or unexplained bone pain, seek immediate medical attention. These could indicate a serious underlying condition.

What It Measures

Alkaline phosphatase (ALP) is a special protein in your body. You find a lot of it in your liver, the tubes that carry bile, and your bones. This test checks how much ALP is in your blood.

Why It's Ordered

Doctors often order this test to check for issues with your liver or bones. They also use it to see if treatments for these problems are helping.

Reference Range

ALP levels can vary based on your age, sex, and other factors, and normal ranges can differ between laboratories. Your doctor will interpret your results based on your individual health and the lab's specific reference range.
