Campbell-Brown, 31, tested positive on 4 May for a banned diuretic. She is suspended pending her "B sample" result, the Jamaican Athletics Administrative Association said, and faces a two-year ban from athletics.
The banned diuretic for which she tested positive at the Jamaica Invitational meet is considered by the World Anti-Doping Agency to be a masking agent.
Campbell-Brown won 200m and 4x100m relay golds at the 2004 Olympics in Athens and retained her 200m title in Beijing four years later. She has won 16 medals for her country in world and Olympic meets and at London 2012 took bronze in the 100m and was a member of Jamaica's silver medal-winning sprint relay team.
