One interesting angle is the possibility of target testing. When asked if she was targeted, UCI-official Van den Abeele was rather evasive:
"Of dit een gerichte controle was? We controleren al een tijdje op de wereldkampioenschappen. De laatste jaren was er ook heisa en hebben we onze technologie aangepast."
"Was it a targeted test? We have been performing tests at the world championships for a while now. Over the last couple of years there was some drama surrounding it and so we adapted our technology."
So, he doesn't really answer the question whether or not the test was targeted. He doesn't say "yes" or "no", but rather iterates that they have been performing tests like this one for a few years.
