Blood doping: present procedures and detection techniques

Area of Science:

• Sports Medicine
• Biochemistry
• Analytical Chemistry

Background:

• Blood doping, including autologous and homologous transfusions, has been used since the 1960s to enhance athletic performance.
• While laboratory methods have improved, only homologous blood transfusions are reliably detectable, leaving autologous transfusions undetected.
• Recent advancements in therapeutic drugs for anemia, such as recombinant erythropoietin and synthetic hemoglobin, present potential avenues for blood doping.

Purpose of the Study:

• To review the current landscape of blood doping detection methods.
• To highlight the challenges in detecting autologous blood transfusions.
• To discuss the implications of novel therapeutic agents on anti-doping strategies.

Main Methods:

• Review of existing literature on blood doping and detection techniques.
• Analysis of advancements in therapeutic drug development for anemia.
• Discussion of direct (molecule identification) and indirect (effect detection) doping detection methods.

Main Results:

• Only homologous blood transfusions are currently detectable; validated methods for autologous blood transfusion detection are lacking.
• Therapeutic drugs like recombinant erythropoietin and synthetic hemoglobin could be misused for doping to enhance oxygen transport.
• Direct detection methods are deterministic, while indirect methods are probabilistic, offering complementary approaches.

Conclusions:

• The evolution of doping-detection methods must keep pace with novel therapeutic approaches.
• A combination of direct and indirect detection methods is crucial for effective blood doping control.
• Future anti-doping efforts will likely rely on both identifying doping agents and detecting their physiological effects.
