London 2017 | Thompson spent nearly seven hours in anti-doping

LONDON, England:

Elaine Thompson spent nearly seven hours in anti-doping after her final on Sunday, because her sample was continuously deemed unsuitable according to World Anti-Doping Agency (WADA) standards.

Thompson's sample failed to meet the specific range of gravity required for testing standards with team manager Ian Forbes, confirming that the star sprinter was among several athletes' whose samples could not be accepted immediately.

Forbes also alleviated concerns that Jamaicans were affected in the gastroenteritis issue, which affected several athletes and officials at an official World Championships team hotel.

WADA has established ranges for a sample's density, which can, according to medical sources prove difficult to meet if athletes are over-hydrated, a note identified in the WADA Code under section 7.5.4, which reads:"The Athlete shall be encouraged not to hydrate excessively, since this may delay the production of a suitable sample."

The absence of enough properties from other rehydration fluids besides water can also lead to an unsuitable sample with one source pointing out that water was the only fluid provided to teams by organisers at the official team hotel and at the competition venue.

"She was there until close to 4:30am," Forbes noted in relation to Thompson, while highlighting that the management has been working to provide other sources of rehydration for the athletes.

"We have been providing rehydration to the team. it has been very difficult to secure it, yesterday alone I bought 100 bottles, so we have been doing it, but it has been a challenge."

The women's 100m final took place at 9:50 p.m.

Another Jamaican sprinter, Jura Levy, had a similar problem and was delayed for over five hours with Trinidadian Michelle-Lee Ahye also among those who had to be kept back until a suitable sample was provided.

After the Local Organising Committee (LOC) confirmed the breakout of gastroenteritis, one of the official team hotels for the championships.

Reports yesterday surfaced that Botswana's Isaac Makwala was among several persons affected by the gastroenteritis situation with the 400m medal favourite forced to miss his 200m heat yesterday

Up to midnight Forbes said that he had not received any reports that any Jamaican was affected.

"No, we have not had any such reports from our end," Forbes confirmed after checking with medical personnel.

In a release last night, the LOC noted:

"There have been a number of cases of gastroenteritis reported by team members residing within one of the official team hotels for the World Championships."

"Those affected have been supported by both team and LOC medical staff, in addition we have been working with Public Health England to ensure the situation is managed and contained," the release read.

"As a result, further advice and guidelines have been issued to team doctors and support staff standard procedure for such an occurrence where a number of teams are occupying championship accommodation."
