Medical Review Officer Services
Certified MRO Services for Employers and Organizations
Dr. Kayur V. Patel provides Medical Review Officer services for employers and organizations that need physician-level review of drug testing results, medical explanations, documentation, and workplace testing processes.
MRO Overview
What a Medical Review Officer Does
A Medical Review Officer, or MRO, provides an independent physician review between the laboratory result and the employer's final reported result.
An MRO may review laboratory-confirmed results, contact the donor when required, evaluate whether a legitimate medical explanation exists, review relevant medical information, and report a verified result to the appropriate employer representative.
The MRO process helps protect the integrity of workplace drug testing by ensuring that certain results are reviewed by a qualified physician before being reported as verified outcomes.
Why MRO Review Matters
Drug testing results can have significant consequences for employees, employers, safety-sensitive work, and workplace operations. A laboratory result alone does not always tell the full story.
MRO review adds a medical layer to the process. It supports accuracy, fairness, confidentiality, appropriate result verification, and defensible decision-making.
MRO Services May Include
Donor interview and medical explanation review when appropriate
Verification of positive, negative, adulterated, substituted, invalid, or cancelled results when applicable
Review of prescription or medical information when relevant
Communication of verified results to the designated employer representative
Support for regulated and non-regulated workplace testing processes
Coordination with laboratories, collection sites, and employer representatives when appropriate
Documentation of MRO review activity
Confidential handling of medical information
Review of laboratory-confirmed drug test results
Guidance on result interpretation within the MRO role
