Detecting human growth hormone (GH) doping in athletes is difficult due to its identical structure to endogenous GH. New marker and isoform approaches offer improved detection methods for anti-doping efforts.
Area of Science:
- Sports Science
- Biochemistry
- Anti-doping
Background:
- Human growth hormone (GH) abuse by athletes presents a significant challenge for anti-doping agencies.
- The identical chemical structure of recombinant GH (rGH) to endogenous pituitary GH complicates detection via standard biochemical tests.
Purpose of the Study:
- To outline and evaluate novel approaches for detecting GH doping in athletes.
- To enhance the effectiveness of anti-doping strategies against GH abuse.
Main Methods:
- The 'marker approach' involves measuring GH-dependent proteins that show abnormal elevations post-rGH injection.
- The 'isoform approach' focuses on detecting alterations in the circulating GH isoform profile after rGH administration.
Main Results:
- Both the marker and isoform approaches provide viable methods to distinguish between endogenous and exogenous GH.
- These methods offer improved sensitivity compared to traditional detection techniques.
Conclusions:
- Wider implementation of these advanced GH detection tests, particularly in out-of-competition controls, is crucial.
- Enhanced detection capabilities will significantly increase the likelihood of identifying athletes engaging in GH doping.
