Abstract
Capillary blood sampled as dried blood spot (DBS) has shown substantial potential as test matrix in sports drug testing in various different settings, enabling the analysis of numerous different drugs and/or their respective metabolites. In addition to established beneficial aspects of DBS specimens in general (such as the minimally invasive and non-intrusive nature, and simplified sample transport), a yet unexplored advantage of DBS in the anti-doping context could be the opportunity of preserving a source of information complementary to routine doping controls performed in urine or venous blood. Whenever follow-up investigations are warranted or required, frequently collected and stored (but yet not analyzed) DBS samples could be target-tested for the compound(s) in question, in order to contribute to results management and decision-making processes.
Keywords: adverse analytical finding; atypical finding; doping; dried blood spot; sport.
