Where is blood doping done

Blood transfusions involve drawing out your own blood and storing it for a few months while your body replenishes its red blood-cell supplies. Then, before the competition, the athlete would re-inject the blood back into his or her body. The outcome is similar to that of EPO — a bump in red blood cells. WADA suggests there has been a resurgence of blood transfusions with the introduction of an EPO-detection method in For athletes, the extra bump can mean the difference between a gold and silver medal , or whether or not you break a world record.

So those would be the sports that just kind of pop right out," Joyner said. He added, "The amount of improvement would be clearly enough to give you a substantial edge in international competitions if you were an elite athlete. The year-old biker reportedly admitted taking EPO during a televised news conference. Microorganisms have been developed to churn out so-called human recombinant EPO, which appears very similar to the body's natural EPO. A recent study led by Lundby of eight males injected with human EPO and then monitored while riding stationary bikes showed poor detection of EPO in independent tests done at two labs.

While so-called Lab A found positive results for all participants during the weeks when the drug was administered every other day, Lab B found no positive EPO tests. Three weeks after the last EPO injection, only two out of 48 urine samples showed up as positive in lab tests.

Volume , Issue 9. Previous Article Next Article. View Metrics. Cited By Web Of Science Email alerts Article Activity Alert. There are three widely known substances or methods used for blood doping, namely, erythropoietin EPO , synthetic oxygen carriers and blood transfusions.

EPO is a peptide hormone that is produced naturally by the human body. EPO is released from the kidneys and acts on the bone marrow to stimulate red blood cell production.

While proper use of EPO has an enormous therapeutic benefit in the treatment of anaemia related to kidney disease, its misuse can lead to serious health risks for athletes who use this substance simply to gain a competitive edge.

It is well known that EPO, by thickening the blood, leads to an increased risk of several deadly diseases, such as heart disease, stroke, and cerebral or pulmonary embolism.

The misuse of recombinant human EPO may also lead to autoimmune diseases with serious health consequences. A blood screening was performed first and a urine test was then used to confirm possible use of EPO. This report also recommended that urine testing be used in conjunction with blood screening for a variety of reasons, including the cost savings of performing blood screening prior to testing urine.

Recently, the urine test used for the detection of some new erythropoiesis stimulating agents was adapted for blood testing. Synthetic oxygen carriers, such as haemoglobin based oxygen carriers HBOCs or perflurocarbons PFCs , are purified proteins or chemicals having the ability to carry oxygen.
