Paula Radcliffe supports calls for an independent body to replace UK Sport as the anti-doping agency for Britain and Northern Ireland.
Former 1,500 metres and mile world record-holder Steve Cram last week made the case for UK Sport to be allowed to focus on their other responsibilities.
Radcliffe, women's marathon world record-holder, says a separate body operating in accordance with World Anti-Doping Agency guidelines could carry out the role more effectively. She said: "There needs to be an independent body with no links to any funding and federations - anything like that. It should be affiliated to WADA so that the rules are the same across the world."
Cram is uncomfortable with UK Sport's role in funding the elite athlete programmes and dealing with anti-doping policy.
Radcliffe also believes Christine Ohuruogu should be allowed to compete for Britain at future Olympic Games, despite missing three out-of-competition tests.
Radcliffe, who advocated four-year bans for first-time drug offenders and life suspension for a second offence at an IAAF anti-drug symposium in Lausanne, wants more understanding to be shown to athletes who miss out-of-competition tests. Missing three tests carries a mandatory one-year suspension, with Ohuruogu the first and only track and field athlete to fall foul of it.
