I'm not an expert on this by any means. However, can there be any tests done for HGH by doing blood tests? There technically is a test, but it's not practical at all. Major League Baseball doesn't test for HGH. The International Olympic Committee brags it has had an HGH test since before the 2004 Olympics, but that is semantics. Yes, there is a blood test for HGH. But because antibodies necessary for the process are in such short supply, virtually no HGH testing is conducted. In addition, the test only detects HGH right after injection so it's impractical for in-competition testing. As a result, there never has been an HGH positive. There have been just a couple hundred HGH tests, according to experts such as Christiane Ayotte, head of the Montreal Olympic-testing lab, and Gary Wadler, a physician and author who has advised the World Anti-Doping Agency.
