Anti-doping agencies try to make sports clean

While sportspersons that dope seek new ways to avoid detection, anti-doping agencies introduce new tools in order to catch those that take banned products. One of new tools introduced into anti-doping system is biological passport. It helps to set whether a sportsperson has used any prohibited preparation. The biological passport measures some biomarkers that can indicate whether an individual has administered certain medicines. So, it can measure hemoglobin levels. Unexplained low or increased hemoglobin levels may indicate doping. So, the biological passport defines physical changes which play great role in detection.
It is obvious that anti-doping policy becomes more progressive. It develops new tools to catch dopers and clean sports.
If you compare drug tests which have been applied earlier with those that are used today, you can understand that the difference is significant. Anti-doping efforts are great. Drug testing becomes more progressive.
It was also developed a test for detection of CERA. This medication was initially developed in order to treat anemia associated with kidney diseases. Since earlier there was not any drug test which could determine 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 athlete had taken CERA. As a result, Rashid Ramzi lost his awards.
Earlier it was hard and even quite impossible to catch those who applied HGH. Lately a blood test for this medicine was also developed.
Another new drug test, known as Isotope Ratio Mass Spectrometry, was also lately introduced. This test helps to define whether testosterone has been administered from outsides or it has been secreted in the body naturally.
So, anti-doping system is more sophisticated today. Anti-doping officials suggest that they will be capable to clean sports from administration of performance-enhancing drugs.
