While the CCES is making every possible effort to make the collection of blood samples as easy and painless as possible for the athletes, if an athlete is prone to fainting when giving blood, it is highly recommended that the athlete have a representative present during doping control. In the event an athlete faints or requires first aid, the phlebotomists on-site will perform first aid.

If the sight of blood makes an athlete nervous, afraid, and/or nauseous, they are encouraged to share those concerns with the blood collection officer and doping control officer.
