At San Diego Lab Testing, we offer Medical Review Officer (MRO) services. Our physician staff member has received his certification from American Association of Medical Review Officers (AAMRO). Our MRO is dedicated to following national standards in the area of drug and alcohol testing.  AAMRO certification is an indication to the public for following the ethical standards and providing high quality service for the benefit of employee, employer, and the general public.

AAMRO certification is recognized as an objective standard of competency and expertise for MROs.

We specialize in DOT and non-DOT testing, from collection, to processing and submission of the specimen, to evaluation of negative and non-negative test results. We work with employees and employers to provide an efficient and secure method of test result verification.

It is vital that a Medical Review Officer (MRO) is involved to deliver expertise and competency in the field of alcohol and drug testing.

So WHY should an MRO be involved in drug and alcohol testing process?


The importance of a certified MRO cannot be overstated. The certified MRO protects the donor from a false accusation of illicit drug use when there is an alternate medical explanation for the laboratory result. At the same time, the certified MRO protects the Company as a valuable resource - helping with policies and regulatory issues, as well as providing related services, such as drug test collections, breath alcohol testing services, coordination of laboratory services, laboratory performance testing, and preparation of summary reports for employers.


Why is certification crucial for MRO work?

Certification is vitally important as sweeping changes to the Drug and Alcohol Testing Rule issued by the Department of Transportation in 2001 has affected more than 7 million workers in the transportation industry. The changes have significantly affected MROs and have expanded their official duties and responsibilities. MROCC certification is the ultimate mark of an MRO's competency and fulfills the requirement set forth in the revised 49 CFR Part 40 Rule. The Medical Review Officer (MRO) is defined through federal guidelines as, “a person who is a licensed physician and who is responsible for receiving and reviewing laboratory results generated by an employer’s drug testing program and evaluating medical explanations for certain drug test results.”


In reality, it is the MRO who has received the necessary training and certification needed to effectively act as the objective and expert safeguard of the entire testing process. The MRO must be and remain knowledgeable about applicable rules including DOT Part 40, MRO guidelines, and any other regulations which impact organizations for whom the MRO evaluates drug test results. The MRO is often called upon to assist clients in the implementation of legally defensible policies and programs. Therefore, the MRO must be able to advise organizations about both regulated and non-regulated drug and alcohol testing procedures. Knowledge in the area of regulatory issues and MRO responsibilities will enable the MRO to serve in a host of settings.

•       MRO services afford you with the most EFFICIENT turn around times on reporting test results

•       While no two tests are alike, so are no two verifications the same. Several factors can influence how quickly results are reported, such as the time and accuracy of the collection, when the lab received the specimen, how many substances must be confirmed at the laboratory, delays in shipments to the lab, etc. etc. With a positive test result, the variables can grow exponentially as a result of when contact was established with the donor, how readily they supply us with the information needed to complete the review, etc. etc. Understanding these variables prevents us from offering one cookie cutter time frame for the reporting of tests following the MRO review, however, the following do represent the average turn around time for the vast majority of our tests:

NEGATIVE test reviews are normally returned within the same business day as they are received from the laboratory.
POSITIVE test reviews are normally returned within 1-3 business days from the time they are received from the laboratory.
