Drugs testing in sport. View of a sample collection kit used to test for illegal use of drugs in sport. Urine is the normal substance collected in these containers which are sealed as a deterrent against tampering. The urine is used to test for all drugs banned by various international and national sporting bodies. The samples are treated with a variety of solvents, and put through chromatography and mass spectrometry in order to detect the smallest traces of banned, performance-enhancing substances.
