British and Commonwealth heavyweight champion David Price has admitted that he has not been drug tested for over three years since turning professional.
Price has admitted that he thinks more can be done in Britain to help combat the use of performance-enhancing substances.
He told BBC Sport: "I haven't been randomly tested since I turned pro, not once in three-and-a-half years.
"I have had urine tests before title fights, but I'd like to see more random blood testing.
"I know expense is an issue, but more could be done, especially in light of what happened with Larry Olubamiwo. He was taking every drug under the sun and that could have ended up in disastrous consequences for someone, given the nature of the sport."
Olubamiwo was banned for four years this summer after being found guilty of multiple anti-doping violations, including the use of EPO.
Price is back in action on Friday November 30, defending his domestic belts against Matt Skelton.
