Review and verification of drug test results

Employers need drug test results reviewed, verified, and documented before they act on them. This process matters for DOT programs, safety-sensitive work, return-to-duty testing, and workplace policies.

Mega Health coordinates MRO support with drug and alcohol testing, pre-employment screening, random testing programs, and employer accounts. Call to confirm the review process and who will receive the results.

Built into the employer TPA workflow

Mega Health separates the administrative, medical review, and recordkeeping pieces so employers can understand what happens at each step. The TPA side helps manage program logistics. The MRO side supports appropriate review and verification of drug testing results. MegaHub TPA then keeps related records visible for employers.

HR teams and safety managers can follow the result through review, confirm who needs to be informed, and track outstanding paperwork.

Local support for DOT and non-DOT programs

Employers in Manassas and Northern Virginia can contact Mega Health Services to discuss current MRO-related workflows for DOT and non-DOT programs, pre-employment testing, random testing, post-accident testing, reasonable suspicion testing, and follow-up requirements.
