Drug Testing

Metro Lab offers comprehensive drug testing solutions to meet a wide variety of requirements. Specializing in both D.O.T and Non-D.O.T. drug testing services, Metro Lab works closely with the National Institute of Drug Abuse (NIDA). We are the laboratory testing facility of choice for a wide customer base, consisting of corporations and local businesses, individuals, government and municipal agencies, Non-Governmental Organizations (NGOs), schools, and court systems. 

Metro Lab provides essential drug and alcohol testing services to meet the workplace requirements of organizations of every type and size. We can assist with pre-employment drug testing, random testing, post-accident, follow-up testing, and much more. Notably, Metro Lab can help your company become compliant with Department of Transportation regulations. We also work with D.O.T.-Compliant Organizations: those with workers considered to be doing “safety-sensitive” jobs by the Department of Transportation. In this case, the D.O.T. requires special treatment for employee drug and alcohol testing. Metro Lab is highly experienced in D.O.T. drug testing and understands the sometimes complex D.O.T. regulations.

Metro Lab features today’s most innovative drug and alcohol testing technologies, and offers a wide array of collection methods, including:

  • Breath (Alcohol and Drug Testing)
