ALPL, or alkaline phosphatase, liver/bone/kidney, is an enzyme found in various tissues throughout the body, including the liver, bones, and kidneys. It plays a crucial role in breaking down proteins and is essential for processes like bone mineralization and liver function. Elevated levels of ALPL can indicate certain health conditions, such as liver disease or bone disorders. Medical professionals often measure ALPL levels through blood tests to help diagnose and monitor these conditions, making it an important marker in clinical practice.
