Drug Testing Process

The drug testing process depends on whether the testing is nonregulated or regulated.

Nonregulated Testing

These tests are usually performed by private companies where there is no government requirement for testing. The standards for nonregulated testing are minimal to nonexistent.

Regulated Testing

These drug tests are required by one of six United States federal agencies and follow strict protocols for collection and evaluation. Most testing protocols use the urine drug test, although some forensic testing for criminal prosecution uses blood testing and various companies use hair analysis. Federal and many company protocols call for the use of breath analysis for alcohol testing because the results are instantaneous.
