There are actually two different ways urine tests are processed. The most common is a drug screen, which generally searches not for drugs, but drug metabolites in the urine.

Drugs are flushed out in the urine. One form of drug testing involves putting a very small amount of urine (a drop or two) on a panel that is sensitive for specific substances that the panel is set up for. A reaction indicates the presence of that substance.

Urinalysis drug tests can be done on-site, or sent to a laboratory. Employers typically have the test sample sent to a laboratory, while probation officers typically test the sample on-site. On-site drug testing is becoming more popular due to cost efficiency.

If you take a specific drug, traces of it will appear in your urine. By mixing your urine with dyes that bond to those drug particles, the testers can see if you've taken drugs based on the change of color in urine.
