Dopage et santé : Le suivi longitudinal en danger : Moins de budget, moins de prélèvements pour le « suivi médical réglementaire » en France, plus connu sous le nom...
As I said originally, WADA's Biological Passport was born out of the FFC's longitudinal monitoring system which happened because of Festina Affair. That's why this article refers to it as 'Longitudinal' - because health isn't simply a moment in time, to fully understand health and performance it has to be profiled like a biological passport, as does training data and much like how e.g. Training Peaks works. They compliment each other in sports science over a period of time.
You'll even read the FFC Dr describes the system as 'protecting their health and prevent the use of doping'
