A sample taken from Wilson, 27 from Lincolnshire, at the Bedford International Games on June 12 was found to contain testosterone and clenbuterol.
She has been provisionally suspended from July 9 pending her response to the charge.
Wilson represented Great Britain for the first time in March at the European Indoor Championships in Paris where she reached the semi-finals of the 60m.
She failed to qualify for last year’s Commonwealth Games but this year beat the Olympic A standard of 7.30 seconds with a 7.25secs personal best.
Wilson – who also competes for Sheffield Hallam University – works as a sport development officer at East Lindsey District Council.
n World junior champion Jodie Williams ran a championship record time to secure gold in the 100m for Great Britain at the European Junior Championships in Tallinn.
The 17-year-old sprinter’s time of 11.18 seconds was also a personal best and the 2012 hopeful felt she won in a difficult field.
“These girls are so talented and they’ve been running good times this season so it wasn’t even a given that I’d medal, but I performed on the day and I’m over the moon,” she said.
“I had hoped today would be the day for a PB so I’m really happy.
“I’ve been training better than last year and my times in training have been better than last year so I knew I had 11.1 in me, I’ve just not had the right conditions until today.”
Fellow Brit Marilyn Nwawulor also reached the final and finished eighth with a time of 11.73secs.
Adam Gemili had to settle for silver in the men’s 100m final but the 17-year-old, who also plays for League One football side Dagenham, was looking forward to the relay final.
He said: “I’m really happy to continue with both football and athletics and I’m really, really happy with that race.”
Katarina Johnson-Thompson was left disappointed despite being able to produce her lifetime best points tally in the Heptathlon, where she finished sixth with 5,787 points.
Katie Kirk and Lucy James finished fifth and seventh respectively in the women’s 400m, while Jarryd Dunn came eighth in the men’s equivalent.
