A Medical Review Officer (MRO) drug test is administered by a licensed physician responsible for receiving and reviewing laboratory results generated by an employer’s drug testing program. The MRO also evaluates drug test results.
In this blog, we’ll dig deeper into the question “What is an MRO drug test?” We will look at the test procedure, the role of the MRO in testing, different types of MRO drug tests, why they are important, and more.

An MRO drug test is used to screen employees for possible substance use. Tests are often performed as part of the employment screening process; randomly throughout an employee’s tenure; or after an employee suffers a work-related accident.
An MRO is responsible for the entire drug testing process, from the initial sample collection to the analysis and reporting of lab results. Per the Federal Motor Carrier Safety Administration (FMCA), “MROs receive laboratory-confirmed urine drug test results; determine whether there is a legitimate medical explanation for a laboratory-confirmed positive, adulterated, or substituted result; and review and report a verified result to the designated employer representative (DER) in a timely and confidential manner.”
An MRO is trained to collect test samples and certified to review laboratory results. MROs are experts in the toxicology of illicit drugs and substances. They must closely follow the chain of custody of drug test samples and keep accurate records to ensure that samples do not lose their integrity or end up in the wrong hands.
The MRO drug test process begins with the collection of a urine sample from the donor. The collection is overseen by the MRO, who then submits the sample to a laboratory where it is analyzed for illicit substances.
Upon receiving the results, several action items occur, depending on if the results are positive or negative. In either case, the MRO reviews the chain of custody for the sample to ensure there were no errors that may have compromised the test results. Beyond that:
If MRO drug test results are negative:
If MRO drug test results are positive:
Substantial drug use can lead to high turnover rates, absenteeism, low-quality work, and more. Substance abuse is particularly harmful in industries like transportation, where an employee’s drug use may hurt not only themselves but others around them, including passengers or others on the road.
An MRO drug test is an important tool for keeping employees and others safe, healthy, and productive. Results are generally very accurate and returned within a matter of days. Some tests, including four panel drug tests, return positive or negative results in only a few minutes, though further laboratory analysis may be required to determine the actual substance the employee may be using.
Let’s explore the MRO drug testing process from start to finish, including the drug testing procedure and reviewing and confirming the test results.
The MRO drug testing procedure starts with the collection of a donor’s urine sample and ends with the analysis and reporting of laboratory test results. It includes:
Once the MRO receives the drug test results from the lab, they must carefully review the results and take steps to ensure their accuracy. This involves:
In the case of a positive MRO drug test result, the MRO will schedule an appointment with the donor to go over their findings. This meeting will cover:
The meeting and any results or treatment plan discussed are held in strict confidence.
There are different varieties of MRO drug tests, including pre-employment drug tests, random drug tests, and post-accident drug tests.
Pre-employment MRO drug tests are used to screen potential employees for substance use before they are hired to perform a job. They are usually one of the last steps before hiring and are an effective tool for keeping drugs out of the workplace.
Employers have the option to initiate random MRO drug tests at any given time and without advance notice. The U.S. Department of Transportation (DOT), for example, requires companies in the transportation industry to conduct DOT-compliant random drug tests on safety-sensitive employees on an ongoing basis. This practice helps companies maintain a drug-free workplace.
In addition, the Drug Free Workplace Act requires that federal agencies, including the Department of Defense, routinely screen personnel for drug use. The U.S. Department of Health and Human Services (HHS) implemented the program which now resides in the Substance Abuse and Mental Health Services Administration (SAMHSA).
Employees who suffer workplace-related accidents may sometimes be prescribed pain-relieving drugs like oxycodone or Vicodin. While legal, these and similar drugs can be highly addictive. Therefore, post-accident drug testing may be required to ensure that employees are not abusing the drugs or continuing to use disqualifying medications beyond the parameters of their prescriptions.
MRO stands for “Medical Review Officer.” Let’s look at what an MRO is, including the professional credentials required to be an MRO and their ethical and legal responsibilities.
To be an MRO, an individual must be a licensed physician (either a Doctor of Medicine or Osteopathy). Both DOT and HHS specify the professional credentials needed to be an MRO and these guidelines can be applied to any drug testing program (both government and non-government). As an example, per the U.S. DOT, that person must have basic knowledge in several areas, including knowledge of:
MROs must also receive qualification training around:
More information can be found in DOT Rule 49 CFR Part 40 Section 40.121. And for HHS/SAMHSA definition of an MRO’s professional credentials, refer to the Medical Review Officer Guidance Manual for Federal Workplace Drug Testing Programs.
An MRO is responsible for validating the accuracy and integrity of the drug testing process. This includes ensuring that drug samples are handled in an appropriate way so that they are not tampered with at any point during the testing process.
Once results are returned and validated, the MRO is responsible for reporting them to the employee and employer in a confidential manner. For federal government drug testing programs, the MRO must also perform all functions in accordance with DOT or HHS regulations.
Let’s examine how MRO drug testing contributes to a safe and productive work environment and the possible legal implications of a positive test result.
Mitigating employee drug use and helping employees with addiction can help address some of the more serious and common problems associated with drugs in the workplace, including adverse impacts on workers’ health and higher insurance costs.
By pre-screening prospective employees before they are hired, an MRO drug test can help keep substance abuse out of the workplace before it even begins. Random MRO drug testing can ensure that employees remain clean during their tenure, and post-accident drug screening can help verify that employees who may have taken prescription pain relievers do not continue to abuse the drugs.
In addition to maintaining the confidentiality of a donor’s test results, the MRO:
Non-federally regulated employers have a lot of latitude when it comes to the courses of action they can take in the event of a positive test result. They could legally opt to arrange for the employee to be enrolled in a treatment program, put the employee on probation, terminate the employee, and more.
However, in federally regulated industries, such as trucking, positive test results and instances of refusal to test must be reported by employers or MROs to the appropriate regulatory body such as the Federal Aviation Administration or DOT/Federal Motor Carrier Safety Administration (FMCSA). In the case of the FMCSA, violations will be listed on the federal Drug and Alcohol Clearinghouse for a period of five years. This database can be accessed by prospective employers seeking screening information about job applicants. The results of a failed DOT drug test will not appear on a criminal background check.
Employees also have legal rights, including the right to be tested in a non-discriminatory way, the right to be notified of testing policies, the right to challenge test results and the right to privacy.
The initial sample collection only takes a few minutes. Transit to a lab can take anywhere between 24 – 72 hours. Testing in the lab is generally very quick, though it can take the MRO up to 96 hours to confirm positive test results, especially if they have trouble reaching the donor.
Donors have the right to contest MRO drug test results. In general, a donor must produce proof that another factor beyond illicit drug use influenced the test result (such as a prescribed medication, environmental factor, or certain type of food) to successfully contest the results.
MRO drug tests are typically very reliable. Although false positives and false negatives do occur, they are rare. The stringent review process involved in analyzing MRO drug test results contributes to the accuracy of the process.
With MRO drug testing, employers can pre-screen potential employees before they are hired, perform random drug tests throughout an employee’s tenure, and screen employees for continued or illicit drug use following a workplace accident. Whatever the tactic, MRO drug testing is a powerful tool that improves worker productivity, safety, and morale while saving employers significant money on drug-related insurance costs.
