The Jamaica Anti-Doping Commission has admitted to procedural breaches during its collecting of a sample from two-time 200 metres Olympic champion Veronica Campbell-Brown in 2013.
The 31-year-old Jamaican athlete's sample taken at a track meet in Kingston last May tested positive for a diuretic, HCT, leading her to being banned for two years by the IAAF - but subsequently overturned in February by the Court of Arbitration for Sport.
CAS were scathing in their written report, describing Jamaican Athletics anti-doping processes as deplorable.
The report says the issue gives rise to the most serious concerns about the overall integrity of the programme.
The Jamaica Anti-Doping Commission says it acknowledges that some procedures carried out in the sample collection process were inconsistent with the World Anti-Doping Agency international standards.
It came out during the hearing that Campbell-Brown failed to pass the required amount of urine on her first attempt.
She was allowed to keep the container to pass the additional amount, which is against international standards.
The organisation says having been restructured, it's continuing to refine and upgrade its procedures.
