PROMISING Jamaican quarter-miler Bobby-Gaye Wilkins is the athlete who returned an adverse analytical finding to her ‘A’ sample at the 13th IAAF World Indoor Championships in Doha, Qatar, between March 12 and 14.

Highly-placed Observer sources have confirmed that Wilkins’ ‘B’ sample has also returned positive.

This means that Jamaica could now lose the 4×400 metres relay bronze medal they won at the meet because the 21-year-old Wilkins ran the first leg of the race. The name and type of the prohibited substance is still not known.

Efforts to contact the United States-based Wilkins, through her agent Oneil Wright, were unsuccessful as the latter’s mobile phone went straight to voicemail.

The other members of the Jamaican mile-relay team at the Doha meet which returned a national record of 3:28.46 were Clora Williams, Davita Prendergast and Novlene Williams-Mills. The United States won the event ahead of Russia.

Jamaica’s other medal at the World Indoor Championships came in the 60 metres where Veronica Campbell-Brown won gold in a personal best 7.00secs.

Meanwhile, the Jamaica Amateur Athletics Association (JAAA) remained tight-lipped on the matter, with president Howard Aris indicating he knew nothing about an adverse analytical finding by a Jamaican.

“You know more than me,” Aris told the Observer yesterday.

Second vice-president of the JAAA, Dr Warren Blake, who served as team leader and doctor for the team to Doha, also told the Observer he could not confirm any adverse analytical finding concerning any Jamaican athlete coming out of the championships.

An adverse analytical finding refers to the “presence of a prohibited substance or its metabolites or markers (including elevated quantities of endogenous substances) or evidence of the use of a prohibited method”, as outlined in the 2010-2011 IAAF’s Competition Rules book.

In accordance with the IAAF anti-doping process, after the “B” sample is returned and any follow-up investigation is carried out, the athlete in question shall be afforded an opportunity, either directly or through his National Federation, within a time limit set by the IAAF, to provide an explanation in response to the anti-doping rule violation asserted.

Subsequent to receiving the result of the ‘B’ sample, the athlete has the right to request a hearing.

“If a hearing is requested by an athlete, it shall be convened without delay and the hearing held within three months of the date of notification of the athlete’s request to the Member,” states Rule 38.9 of the 2010-2011 IAAF Competition Rules book.

Last year, Jamaicans Lansford Spence, Marvin Anderson, Yohan Blake, Allodin Fothergill and Sheri-Ann Brooks returned adverse analytical findings for the banned substance 4-Methyl-2-Hexanamine at the National Trials, ahead of the Berlin World Championships.

Brooks, who was initially cleared by the Jamaica Anti-Doping Appeals Tribunal, later accepted a three-month ban from the IAAF, ending February 12 this year. The other four served three-month suspensions, ending December 2009.

Other Jamaicans to have tested positive for banned substances include sprinters Merlene Ottey (Nandrolone); Julien Dunkley (Boldenone); Steve Mullings (Testosterone); Patrick Jarrett (Stanozolol); shot-putter Dorian Scott (marijuana); and long/triple jumper Suzette Lee (Salbutamol, which is used for the treatment of asthma, chronic bronchitis and other breathing disorders).
