The current test, based on immunoassays, is robust and reliable.
Another blood test, in its final development stage, will be combined with the current test to further enhance the detection window for hGH abuse. This test, the development of which has been partly funded by WADA, is based on biomarkers.
The concepts and development of both hGH tests have been systematically reviewed by international independent experts in such fields as hGH, endocrinology, immunoassay, analytical chemistry, pharmacology, laboratory work, anti-doping, etc, and published in international scientific journals.
Research was initiated by the International Olympic Committee (IOC) and the European Union, and then taken over by WADA – created in late 1999 – when it launched its scientific research program in 2001.
