Efficacy of new methods introduced by anti-doping officers

While athletes that dope find new ways to avoid detection, anti-doping agencies create new techniques in order to catch those who apply prohibited products. One of new techniques elaborated into anti-doping system is biological passport. It helps to set whether an athlete has doped. The biological passport measures several biomarkers which may indicate whether an individual has used certain medicines. Thus, it can measure hemoglobin levels. Unexplained low or high hemoglobin levels may indicate doping. Thus, the biological passport defines physical changes which play great role in detection.
It is clear that anti-doping policy becomes more advanced. It introduces new tools to catch dopers and make sports free from doping.
If you compare drug tests that have been used earlier with those which are utilized nowadays, you may understand that the difference is great. Anti-doping efforts are great. Drug testing becomes more advanced.
It was also introduced a test for detection of CERA. This preparation was initially created in order to cure anemia connected with kidney disorders. Since earlier there was not any drug test which could define metabolites of this substance, Rashid Ramzi of Bahrain avoided detection at the Beijing Olympics. Recently his sample was re-tested by this new test. Anti-doping officials determined that this sportsman had applied CERA. As a result, he was stripped of his awards.
Earlier it was difficult and even quite impossible to catch those who applied HGH. Lately a blood test for this preparation was also elaborated.
Another new drug test, known as Isotope Ratio Mass Spectrometry, was also lately developed. This test helps to define whether testosterone has been applied from outsides or it has been secreted in the body naturally.
So, anti-doping system is more sophisticated today. Anti-doping officers suggest that they will be capable to make sports free from administration of performance-enhancing drugs.
