"This is serious," he tells Expressen.

Wrestler Jenny Fransson tested positive for anabolic steroids and risks four years of suspension. But she can also be completely freed.

Her agent Mats Larsson, who is a physicist, believes that the analysis done by the anti-doping lab at Huddinge Hospital is not reliable. That the laboratory misunderstood how to assess if the test was positive.

The misunderstanding has led Larsson to report the doping lab to the International Anti-Doping Organization Wada.

-If a laboratory has not understood what is in a technical document, then it must be reported. It is my duty to report it, I have to do it, he tells Expressen.

Wada could question the doping lab's authority.

The acting head of the laboratory in Huddinge, Anton Prohanka, writes in a comment to Expressen that one cannot comment on an ongoing case but that the lab is accredited by Wada and meets its requirements.
