For Employers

Construction Drug Testing

Construction has some of the highest injury and fatality rates of any industry, and post-injury opioid and fentanyl use is a real risk. A testing program protects your crew, cuts workers’ compensation exposure, and can earn insurance credits.

Why construction tests

Heavy equipment, heights, and power tools make impairment catastrophic. Many states offer workers’ comp premium discounts for a qualified drug-free-workplace program, and post-accident testing is central to liability defense.

The right program for job sites

Run pre-employment on every hire, keep post-accident kits in the trailer, and use a 12-panel so fentanyl is covered.

How LabX serves contractors

Talk to a licensed physician

Test results support workplace decisions but are not a medical diagnosis. Anyone with questions about a result or their health should talk to a licensed physician. Employer screening results are reviewed by licensed and trained Medical Technologists; LabX does not currently offer Medical Review Officer (MRO) review, and employers can speak with a LabX toxicologist about a result.

Does drug testing lower workers’ comp costs?
In many states a qualified drug-free-workplace program earns a workers’ comp premium credit and strengthens post-accident liability defense.
Should construction test for fentanyl?
Yes — post-injury opioid and fentanyl use is a real risk; use the 12-panel which includes fentanyl.
