Top Drug Testing Companies for Employers in 2027

Placing an order with a drug testing provider is easy. The follow-up steps are where the process can feel more complicated: Can your candidate find the right collection site? Can your team track an outstanding test? And who helps when something with your screening goes wrong?

As you plan for 2027, you should compare your drug testing company options on the full program they support, from hiring through ongoing employee testing. Your strongest choice will meet your needs, even when those needs extend beyond the individual test orders.

Key Benefits of Choosing the Right Drug Testing Partner

The right provider should help your team with the following tasks:

• Manage testing beyond hiring. They should assist with your random, post-accident, reasonable suspicion, return-to-duty, and follow-up testing needs where applicable.
• Resolve exceptions. The right company can handle your collection problems, outstanding results, expired orders, and questions that require medical review.
• Match services to each location. Your best option will have actual clinic capabilities and hours that fit your worksites.
• Connect screening and compliance. The right drug testing company will have the reporting, policy support, and integrations your team needs to consistently manage your screening program.
