HOW TO CONDUCT A LEGAL DRUG TEST
Step 1 – Once the employee has been informed of their employer’s drug testing policy, they should fill out a Drug Test Release Form and return it to their employer or appropriate department.
Step 2 – In order to perform a test on the employee, a physical sample must be taken and submitted to a lab for testing. On the Substance Abuse and Mental Health Association’s (SAMHSA) website you can find a list of certified laboratories which perform drug/alcohol testing.
Step 3 – The lab will give the results of the drug/alcohol testing to the employer once the testing is complete. The employer then has the right to perform whatever action they deem necessary and, in the case of a positive result, the employee has the right to explain their result.
