Program Design

Keep DOT and non-DOT testing cleanly separated

Employers should define which roles are regulated, what testing reasons apply, who can order tests, who receives results, whether alcohol testing is required, and how documentation is retained.

Drug testing should connect with occupational medicine, pre-employment physicals, DOT physicals, and the Employer Resource Center.

DOT-regulated employers should review official testing requirements and align policies with qualified legal or compliance guidance.

FAQ

Drug Testing FAQs

What occupational medicine services do Tampa Bay employers usually need?

Most employers need a mix of pre-employment physicals, drug testing, DOT physicals for regulated drivers, respirator clearance or fit testing for exposed roles, OSHA documentation, injury evaluation, and return-to-work support.

Can occupational medicine be set up as an employer program instead of one-off visits?

Yes. Castellan Health can help employers standardize ordering, scheduling, documentation, and communication so HR, safety, and operations teams have a repeatable workforce health workflow.

How should employers estimate occupational medicine costs?

Useful cost planning starts with employee count, annual hiring volume, DOT driver count, safety-sensitive roles, respirator users, expected drug testing volume, and likely injury visits. A custom employer quote is still needed for final pricing.
