- 8:09 PMYahoo Sports — Jonah Koech gets US title stripped and a three-year ban for blood doping
"Last year's U.S. 1,500-meter champion Jonah Koech's title was stripped and he received a three-year ban for blood doping, the U.S. Anti-Doping Agency announced Monday. The Kenyan-born 29-year-old's ban came after abnormal results on what's known as his athlete biological passport — a baseline test performed on athletes when they enter the drug-testing pool against which later results are compared. USADA said passport tests that produce “blood biomarkers” and have been used since 2009 are effective in detecting blood-doping methods such as the use of transfusions and the use of blood-boosting drugs like erythropoietin (EPO).
