By means of the test set Testosterone-RIA SSW age-depending areas within the normal of the total hormone level of testosterone in the serum was established in 122 healthy male test persons. The examination resulted in an increase of the testosterone concentration from the 20th to the 55th year of age and a following exponential decrease. The exactness of the intraassay lies in the mean region of concentration at 8-12% and the exactness of the interassay between 10-20%. The sensitivity of the determination is 2.7 +/- 1.8 nmol testosterone/l.
