The IAAF has started using a biological passport program to help fight doping in track and field.

The International Association of Athletics Federations said the “Athlete Biological Passport” program is in effect.

The IAAF said “an ambitious and unprecedented blood-testing program will be conducted at the forthcoming IAAF World Championships in Daegu with the aim of establishing the participants’ full ABP ‘fingerprint.”’

The biological passport program monitors selected biological markers in athletes, whose abnormal variations could be indicative of doping. Cycling also uses the passport method to catch cheaters.
