Drug tests become more progressive

While sportspeople that dope find new methods to avoid detection, anti-doping agencies introduce new techniques in order to catch those that apply prohibited products. One of new tools introduced into anti-doping system is biological passport. It helps to determine whether a sportsperson has applied any banned substance. The biological passport measures certain biomarkers that can indicate whether a person has taken certain medicines. Thus, it can measure hemoglobin levels. Unexplained low or enhanced hemoglobin levels may indicate doping. Thus, the biological passport determines physical changes that play significant role in detection.
It is clear that anti-doping policy becomes more sophisticated. It develops new tools to catch dopers and clean sports.
If you compare drug tests that have been applied earlier with those which are applied today, you can notice that the difference is significant. Anti-doping efforts are great. Drug testing becomes more progressive.
It was also created a test for detection of CERA. This product was originally created in order to cure anemia associated with kidney disorders. Since earlier there was not any drug test that could determine metabolites of this substance, Rashid Ramzi of Bahrain could avoid detection at the Beijing Olympics. Recently his sample was re-analyzed. Anti-doping officers defined that this athlete had applied CERA. As a result, Rashid Ramzi was stripped of his awards.
Earlier it was hard and even quite impossible to catch those that applied HGH. Recently a blood test for this product was also created.
Another new drug test, known as Isotope Ratio Mass Spectrometry, was also recently developed. This test helps to determine whether testosterone has been administered from outsides or it has been produced in the body naturally.
So, anti-doping system is more sophisticated today. Anti-doping officials suppose that they will be able to clean sports from administration of performance-enhancing drugs.
