EtG for recent drinking, PEth for a multi-week window, breathalyzer for immediate results. Used in custody monitoring and employer programs.

Nail and sweat patch

Longer look-back or continuous monitoring when hair or urine is not the right tool.

Mobile employer testing

We collect at workplaces, job sites, and law offices in DFW so staff do not leave the site.
