Drug and Alcohol Testing, DOT Medical Certificates

Urine, hair, alcohol and instant drug testing.

OHS offers laboratory based (MRO review) urine drug and alcohol testing.  Whether you need preemployment, post accident, random, reasonable suspicion or follow up drug testing,  Our SAMHSA certified labs will follow all proper procedures to ensure compliance with DOT agencies: FMCSA, FAA, FRA, FTA, PHMSA and USCG.  

Many non regulated or non-DOT employers conduct random drug and alcohol testing.  OHS can offer different urine panels including a 5 and 10 panel specific to your companies needs. OHS can also perform immediate drug testing with negative same day results.

Consortium Random Testing Program

This is a random drug testing pool that includes multiple companies.  Perfect for owner operators and stand alone accounts.  All regulated employees enrolled into the consortium are eligible for selection of random drug or alcohol tests.  Once the required random testing percentages are met, all companies in the consortium are in compliance.
