According to information provided by NADA (German National Anti-Doping Agency), all blood samples that had been taken at the 10th Challenge Roth were again negative. As a part of the so-called pre-competition tests, blood samples had been taken from 42 athletes in accordance with the WADA Operating Guidelines for the Athlete Biological Passport.

Again, it was not necessary this year to impose any preliminary suspensions since no increased or in any way suspicious blood values were ascertained. After the competition on July 10, 27 samples were taken from 25 athletes, 25 urine samples and 2 blood samples. The examination of the samples in accordance with the WADA Anti-Doping Regulations did not reveal any signs of prohibited substances or the application of prohibited methods. On the whole, 69 samples were taken from 57 athletes before and after the competition.
