Excerpts form article:
"A test for synthetic HGH was first uses, sparingly at the 2004 Athens Summer Olympics. But it did not turn up a single positives, nor did it in more than a thousand tests in 3 subsequent Olympics. The test was able to catch doping only within hours of injection.
But beginning with British rugby player Terry Newton's positive result in February 2010, 7 athletes worldwide have now tested positive for HGH.
The difference is that by early 2010 antidoping scientists had compiled enough data to understand with greater precision the threshold that should trigger a positive...
With better data on the normal human range, scientists have cut in half the ratio that triggers a positive, making the test more sensitive and extending the window to catch a cheater by a day or two...
"If you don't blood test, you essentially give players a license to use HGH," says Travis Tygart, CEO of the US Anti-Doping Agency. "To have a deterrent effect, athletes have to have a real risk of being caught."
