GLASGOW (AFP) - Nigerian teenage weightlifter Chika Amalaha faces a hearing before the Commonwealth Games Federation on Friday over her failed drugs test.

Amalaha, whose A sample failed a control after claiming gold in the women's 53kg category on July 25, also produced a positive B sample.

The tests revealed traces of diuretics and masking agents.

CGF chief executive Mike Hooper said the follow-up examination backed up the initial finding of the doping control that Amalaha went through after her victory in the 52kg class at the Clyde Auditorium seven days ago.

Hooper said on Friday: "I can report that the analysis on the Nigerian weightlifting Chika Amalaha's B sample has been completed, and this has confirmed the analysis and finding of the A result."

Amalaha snatched a best of 85kg before managing 111kg in the clean and jerk for a total of 196kg, to become the youngest Commonwealth weightlifter gold medallist.
