The team arrived at the Valdebebas training centre in the morning, causing a delay of over an hour to the scheduled training session.
The visit was part of LaLiga's routine anti-doping efforts, which involve testing players from all teams in the league, including Real Madrid's senior squad.
Real Madrid's management is unhappy with the timing of the visit, feeling it was poorly coordinated with the team's schedule.
When asked about the delay, Real's coach Xabi explained that the team had no control over the situation and that the delay was the only consequence.
