National junior record holder, Briana Williams has returned a positive test for the banned diuretic Hydrochlorothiazide.

Williams who finished third in the women’s 100-metres at the national senior trials was expected to be a part of Jamaica’s team to the 2019 I-Double-A-F World Championships, in Doha, Qatar.

Williams’ B sample has reportedly confirmed the presence of the substance.

The tests were carried out at the National Senior Championships in June.

Williams’ team has pointed to a contaminated cold and flu medication, which she had declared on her testing protocol form, as the source of the banned substance.
