Alkaline phosphatase normal range: Understand the Alkaline Phosphatase (ALP)

Understand the Alkaline Phosphatase (ALP) test – its purpose, normal range , procedure, and how to interpret results to assess liver and bone health effectively. Normal ranges of alkaline phosphatase (ALP) in the blood in children and in pregnancy are very different at the values presented here. In that case you must use the respective reference tables. The normal range for alkaline phosphatase (ALP) in adults typically falls between 20 to 140 International Units per Liter (IU/L) , though laboratory reference ranges can vary and are influenced by individual factors like age and pregnancy. Normal ALP levels for adults typically range from 44-147 U/L , though reference ranges can vary slightly between laboratories. Women may see temporary increases during pregnancy, and post-menopausal women might have slightly elevated levels.
