ABP: Athlete Biological Passport



The Doping Control Program that is currently taking place is an effective method to detect the marker(s) or evidence of prohibited methods use, nevertheless, it was not easy to detect if an athlete is taking intermittently or a small amount of drug. WADA first proposed the Athlete Biological Passport(ABP) in 2002 since the need for a more sophisticated doping control program has been emerged to fight against developing the resistance to substance and evolving the use of a prohibited method.


Two Modules of Athlete Biological Passport :

  • Haematological Module It was introduced in 2009 to identify the use of erythropoietic stimulating agents(ESA), any form of blood transfusion or manipulation. This module analyzes the ABP blood sample collection of athletes.
  • Steroidal Module It was introduced in 2014 to identify the substance related to steroid doping (detects testosterone, designer steroids, anti-estrogens etc). This module analyzes the urine sample collection of athletes.

KADA will extend the ABP Program to high-risk sports for doping. The medical and biological data of athletes who have been notified that they are selected for the ABP Program will be collected through repetitive testing. The following makers are considered within the ABP Haematological and Steroidal module.


ABP Haematolgical module markers


Haematological Module markers
HCT Haematocrit
HGB Haemoglobin
RBC Red blood cell (erythrocyte) count
RET% Reticulocytes percentage
RET# Reticulocyte count
MCV Mean corpuscular volume
MCH Mean corpuscular haemoglobin
MCHC Mean corpuscular haemoglobin concentration
RDW-SD Red cell distribution width (standard deviation)
IRF Immature reticulocyte fraction
OFFS OFF-hr Score
ABPS Abnormal Blood Profile Score (ABPS)
