The IAAF in 2012, as they wrote in their litte propaganda piece some five years ago:
"Ms Radcliffe's (anonymised) profile was referred for independent expert review"
That is only done after it is flagged as "likely doping".
And yes, according to the IAAF, those experts didn't classify that as an "adverse passport finding", which of course doesn't mean much, as the cases of the EPO users Kiprop and Poistogova show.
Interestingly, the IAAF also wrote that "Ms Radcliffe was target tested for rEPO on every occasion that the applicable IAAF regulations required". LOL
