The test can also be carried out on body hair, so athletes with bald or wet-shaved heads would also expect to be caught out...
Although no definitive test yet exists for the detection of rhGH, there has been some progress of late. One method measures the amount of the 20-kD isomer in the serum, which is present at a level of 10% in normal samples but is suppressed when rhGH is given. This method has shown promise of detecting rhGH within 24 hours of the last dose; however, it requires a blood test and cannot detect cadaveric hGH.
There is mention of scientists developing a urine test that can detect HGH but your links are dated and there is no mention of it being used in the field but rather just mention of it being developed.
