Common Test Methods

  • Urine

The drug screening includes taking the urine sample for testing whether a person takes drugs or not. The sample will go through three phases to confirm the presence of drugs. It is used in random testing programs, and many existing employees can be asked for the test.

If anyone is suspected of the intake of illegal drugs, then this random test takes place on him. It is easy to detect whether any person has consumed alcohol or other drugs recently. It is considered as the approved method, and many regulated and non-regulated employers prefer it.

  • Hair

If an employer is considering the long detection span, then a hair sample can give the result. It is easy to detect the use of drugs within the past three months. If you are confirming the intake of alcohol, then it will not give any result.

The lab technician takes at least 100 strands close to the scalp of the candidate as a sample. If positive output comes, then it is easy to reveal the consumption of drugs.
