What is the normal value range for alkaline phosphatase as part of liver function tests?

10-30 IU/L
30-120 IU/L
120-200 IU/L
200-300 IU/L

The correct answer is: 30-120 IU/L

The normal value range for alkaline phosphatase as part of liver function tests is considered to be between 30 to 120 IU/L. This enzyme plays a significant role in the breakdown of proteins and is primarily found in the liver, bones, kidneys, and bile ducts. Elevated levels can indicate liver disease, bile duct obstruction, or bone disorders, while lower levels are generally less concerning in adults. This range can vary slightly based on the laboratory that performs the test due to differences in equipment and techniques. However, the accepted normal range of 30 to 120 IU/L is widely recognized in clinical practice. Awareness of these values helps in identifying potential abnormalities in liver function or other health conditions related to alkaline phosphatase levels.
