While misuse of testosterone esters is widespread in elite and recreational sports, direct detection of intact testosterone esters in doping control samples is hampered by the rapid hydrolysis by esterases present in the blood. With dried blood spot

Dried blood spot (DBS) testing allows fast, easy, and minimally invasive collection of microvolumes of blood. In an anti-doping context, DBS testing has particular relevance for substances prohibited in-competition only such as ephedrine, which is cu

Testosterone treatment stimulates the production of red blood cells and alters iron homeostasis. Thus, we investigated whether the 'haematological module' of the athlete biological passport (ABP) used by the World Anti-Doping Agency can be used to in
