Biological Passport

The Athlete Biological Passport (ABP) is an electronic record of an athlete's biological values that is developed over time from multiple collections of blood and urine samples.

The ABP is currently composed of two modules:

  • The Haematological Module, introduced into our testing programme in July 2012, aims to identify enhancement of oxygen transport, including use of erythropoiesis-stimulating agents (ESAs) and any form of blood transfusion or manipulation.
  • The Steroidal Module, introduced in January 2014, aims to identify endogenous anabolic androgenic steroids (EAAS) when administered exogenously (i.e. not created by the human body) and other anabolic agents, such as selective androgen receptor modulators (SARMS).

The Haematological Module considers a panel of biomarkers of blood doping that are measured in an athlete’s blood sample. The Steroidal Module considers a panel of biomarkers of steroid doping measured in an athlete’s urine sample.
