Most of the drug testing in sports aims at the performance enhancing drugs. Typical culprits are athletes who take testosterone to build muscles and erythropoietin which builds strength by intensifying red blood cell amount to carry oxygen. Drug testing is also done for cocaine and even alcohol and other banned list of drugs.
The labs uses a scientific sorter technique known as chromatography to detect the drugs. Chemists will simplify a mixture into its constituents depending on their molecular weight, acidity, or readiness to disperse in water. They pass a sample upon a column filled with a material, like silica, a finely crushed glass which combines with the mixture to isolate it. Molecules will get separated by the time they take to run over the column. Then, technicians will find the mass of every molecule. These two measurements jointly serve as an indication for a drug.
Sensitive testing can explain difference between testosterone which is made synthetically or naturally produced in the body by considering carbon. Synthetic testosterone is deficient in carbon thirteen. In this way they can detect the small quantities of synthetic testosterone in athlete's urine.
Chemists test for erythropoietin in other way as it is a large protein. A high molecular weight (30,000 compared to 400 for a steroid), is too big to pass over a column. Technicians attach a sample in a gel and pass it under an electrical field and identifies erythropoietin molecule based on its weight.
