RIO DE JANEIRO (AP) — Ana Claudia Lemos, the Brazilian record holder in the 100m and 200m, tested positive for the anabolic steroid oxandrolone, the Brazil Anti-Doping Authority said on Thursday.
In a statement to The Associated Press, the authority only confirmed the case, and said Lemos requested the B sample be tested.
Brazil’s athletics confederation said in another statement that it was still to be informed of the case.
The 27-year-old Lemos is Brazil’s biggest hope for a medal in the 4x100m relay at the Rio Olympics.
Lemos’ coach, Katsuhico Nakaya, could not be contacted by the AP.
Lemos ranked tied for 23rd in the world in the 100m last year with a personal-best 11.01 seconds.
