Epo is a hormone sometimes misused by athletes to boost their endurance. Since the test to identify the drug's presence was introduced in 2000, 33 labs have been accredited by the World Anti-Doping Agency to administer the procedure. A research team has examined test results at two WADA labs, and found the detection power at the labs was poor.
