Results depend on your age and amount of lean body mass.Another way of expressing the normal range for test results is: 14 to 26 mg per kg of body mass per day for men (123.8 to 229.8 µmol/kg/day) 11 to 20 mg per kg of body mass per day for women (97.2 to 176.8 µmol/kg/day) Normal value ranges may vary slightly among different laboratories.
