Irish swimmer Michelle Smith's backup drug test showed the same signs of tampering as her first specimen, the sport's governing body confirmed Monday.
"The result of the analysis of the B sample confirms that of the A sample," the international swimming federation (FINA) said. "These results indicate suspicion of physical manipulation of the sample."FINA said the case would be forwarded to its Doping Panel for investigation. Smith has 28 days to decide whether she wants a hearing.
Under FINA rules, Smith could be banned for life for manipulating a drug test.
Smith, winner of three gold medals at the 1996 Olympics, underwent an out-of-competition test Jan. 10 at Kilkenny County, Ireland. The urine specimen was divided into A and B samples and sealed in separate containers.
FINA announced last month that Smith's A sample, tested at the IOC-accredited laboratory in Barcelona, Spain, showed "unequivocal signs of adulteration" and "physical manipulation." The sample allegedly contained a lethal dose of alcohol.
Smith's B sample was tested Thursday at the same lab in the presence of her lawyer and a biochemist from a Dublin hospital.
Smith has denied tampering with her test and said any manipulation must have taken place after it was out of her sight.
