Interpretive Data:
Liver alkaline phosphatase can affect the measurement of bone specific alkaline phosphatase in this assay. Each 100 U/L of liver alkaline phosphatase contributes an additional 2.5 to 5.8 ug/L to the bone specific alkaline phosphatase result.
NOTE: Reference intervals have not been established for children younger than 7 years of age or males 18-24 years.
