Some specialists claim that blood tests for HGH are ineffective

NFL players do not trust methods used by the WADA. Why did the distrust appear? Let try to understand the reason.
The World Anti-Doping Agency (WADA) decided to test players of the National Football League for HGH. Althogh the NFL Players’ Association has agreed, several skeptic arguments connected with the level of trustworthiness of blood test for HGH were expressed. This test is going to be just a part of the testing for anabolic steroids and other performance-enhancing drugs.
Some scientists who are not connected with the WADA activity directly don’t agree with the methods used by this agency. They justify the skepticism of the NFL players.
Matt Chaney, a main chronicler of administration of steroids in American football, confirms that players of the NFL are skeptic to the WADA anti-doping tests not without any reason. Skeptic attitude of the players is justified by Matt Chaney.
Don Catlin, the director of Anti-Doping Research, says that methods of the WADA for detection of HGH have to be transparent. The WADA uses the HGH isoform ratio test elaborated by Christian Strasburger.
It is important to note that according to several specialists, the method of this test doesn’t have scientific basis. It is not trustworthy. The Director of Anti-Doping Research notes that this test is not good for detection of HGH at all.
There is another test that can be applied by the WADA to identify sportspersons that administrate HGH. Sonksen elaborated a certain HGH testing method which is based on physiological biomarkers. But the WADA doesn’t applies the method of Sonksen to identify users of HGH.
According to Sonksen, workers of the WADA are not specialists in this area. That’s why they do not see the priority of one method over the other. But as it was proved by specialists, the HGH biomarker test is more useful than HGH isoform test.
However experts confirm about difference between these two tests, the WADA doesn’t intend to to use the other method.
