Linford Christie has undergone three random drug tests this year, even though doping officers did not know his home address.
Staffan Sahlstrom, a Swede who runs the International Amateur Athletic Federation's out-of-competition dope testing programme, said Christie had been tested twice in Britain and once in the US this year.
It was claimed during ITV's World In Action programme on Monday that the British Athletic Federation had undermined its "no notice" programme by failing to pass on Christie's address to the Sports Council, who conduct tests in the United Kingdom.
But Sahlstrom said Christie had been summoned to one test in Britain while the other had been carried out at an unannounced visit to the sprinter's training track by an official.
