David Howman, director general of the World Anti-Doping Agency, says the new procedure will be used alongside the existing test for HGH.
Howman says "it's something that underwent a strong period of scrutiny but it's now in place."
The first test for HGH was only introduced at the Olympics in Athens in 2004.
Weightlifter Pat Mendes — the top-ranked American in the over-105-kilogram weight class — became the first U.S. athlete in an Olympic sport to test positive for HGH and be disciplined for it. He was banned for two years in April.
