New Employee Drug Testing

We’ve worked with business’s to provide pre-employment substance abuse and background checks. A safe workplace ensures the stability of the company and minimizes insurance risks due to unsafe or unstable employees.

Make an appointment or Walk-In at our location for pre-employment drug testing. By default all pre-employment screening includes basic urine test. Other tests such as hair, fingernail and others are available upon request and billed separately. Test results can vary by test; some results within minutes or can take up to one to five days.

Random Drug Testing

Saliva / oral fluid-based drug tests can generally detect use during the previous few days. Is better at detecting very recent use of a substance. THC may only be detectable for 2–24 hours in most cases. On site drug tests are allowed per the Department of Labor. Detection in saliva tests begins almost immediately upon use of the following substances, and lasts for approximately the following times:

Reasonable Suspicion

Some states have established laws that only allow drug screening of employees when reasonable suspicion is present.  Also called, "probable-cause", testing is required when employers notice behavior that leads them to suspect substance abuse. MD Toxicology Labs offers Reasonable Suspicion Training for employees and supervisors.  Reasonable suspicion/causes may include instances like:

  • Signs of diminished efficiency
  • Improper or unsafe conduct with employees and clients
  • Consistently late to work

Written substance abuse policies regarding suspected violation as well as observation of the violation by another employee allows sufficient request for drug testing.

Employee Accidents

One of the first questions after a workplace-related accident involves finding the cause. Oftentimes, investigators want to determine if alcohol or drugs were related to the accident so that proper discipline and liability claims may be mitigated.

A 2006 national study showed that more than 15% of employees drank alcohol before coming to work, used alcohol during the workday, were under the influence of alcohol during the workday or came to work with a hangover at least once in a 12-month period.
