An employee drug testing facility is one where the employer or agent of the employer performs a preliminary preemployment screening procedure for a controlled dangerous substance on a job applicant.

An employer or agent of the employer shall register the employer initially and every 2 years thereafter with the OHCQ by submitting to the OHCQ a registration form that lists the permanent office location of the employer and any agent of the employer in the State; the permanent locations where the employer or agent of the employer performs preliminary screenings; and states whether the employer or agent of the employer performs preliminary screenings at temporary sites, uses mobile screening vehicles, or both.

OHCQ is responsible for the oversight of employee drug testing facilities, including licensure and investigation of complaints.​

To apply for a license for a Employee Drug Testing (EDT) facility, submit the ​Maryland State Employee Drug Testing Registration Application.

There is no fee to apply for a Maryland EDT Registration.  Please remember to include with the mailed original signature application, copies of the chosen director's highest degree earned, and CV.  After a completed application and all requested information is received by OHCQ, it takes 2 - 3 weeks to receive a license.
