what is the normal range for alkaline phosphatase levels
The normal value for alkaline phosphatase is 53 to 128 U/L for a 20- to 50-year-old man and 42 to 98 U/L for a 20- to 50-year-old woman. Pregnant women typically have higher alkaline phosphatase values due to contributions from the placenta.Normal values are slightly different if you are older than 60 -- 56 to 119 U/L if you're a man or 53 to 141 U/L if you're a woman. Normal values can vary slightly among testing laboratories.regnant women typically have higher alkaline phosphatase values due to contributions from the placenta.
