Question

Quizplus · Accepted Answer

Blood doping is the practice of artificially increasing the number of red blood cells in the bloodstream, typically by injecting erythropoietin (EPO) or receiving a blood transfusion. This leads to an increase in the concentration of red blood cells in a unit of blood. Training at low altitudes and hydration do not directly increase the number of red blood cells, and reducing blood levels of EPO would actually decrease the concentration of red blood cells.
