What does 49 CFR 40.151 (What are MROs prohibited from doing as part of the verification process?) require?

Generated guidance. Confirm the source and its applicability before you act. How we check sources.

As an Ask X3 fleet-compliance assistant, I can inform you that according to 49 CFR 40.151, Medical Review Officers (MROs) are prohibited from doing the following during the verification process:

* Using non-compliant tests: You must not consider any evidence or results from drug tests that were not collected or tested according to part 40 rules (such as an employee providing a specimen to their own physician).

* Resolving collection-site disputes: You cannot decide factual disputes between an employee and a collector regarding collection-site events that are not recorded on the CCF (such as claims that a collector left the area or left containers accessible).

* Judging test justification: You cannot determine whether the employer had proper grounds to require a test, such as whether an employee was wrongly selected for a random test or ordered to take a reasonable suspicion or post-accident test without proper grounds.

* Accepting non-medical excuses for positives: You cannot accept explanations of confirmed positive, adulterated, or substituted results that do not constitute a legitimate medical explanation. This includes stories about unknowing or passive ingestion (such as someone slipping drugs into a drink, eating a marijuana brownie, or riding in a car with people smoking crack).

* Accepting Schedule I drug recommendations: You must not verify a test as negative based on a physician's recommendation to use a Schedule I drug, including state-authorized "medical marijuana."

* Accepting hemp, non-prescription marijuana, or coca tea use: You must not accept the use of hemp, non-prescription marijuana-related products, or coca teas as a legitimate medical explanation to verify a marijuana or cocaine test as negative.

* Accepting medical explanations for certain drugs: You must not accept any assertion of a legitimate medical explanation for the presence of PCP, 6-AM, MDMA, or MDA in a specimen.

* Accepting physiological excuses for adulteration: You cannot accept claims that soap, bleach, or glutaraldehyde entered a specimen through physiological means, as there are no such physiological ways for these substances to enter a specimen.

* Accepting physiological excuses for substitution: You cannot accept claims that an employee can physiologically produce a urine specimen with a creatinine level below the laboratory's limit of detection.
