Abstract
Urinary 17-hydroxy-corticosteroids and 17-ketosteroids were determined in 172 healthy male and female subjects of all age groups between 0 and 90 years. By multiple regression analysis of the data of 150, excretion levels were shown to be correlated with age, body weight and height. The effects of these factors were the same in both sexes, but they differed for the 2 steroid fractions. The dependence on physical data was more pronounced for the 17-ketosteroids. From the multiple regression equations, graphs of expected normal excretion were constructed for subjects of average body weight and height.
