MRO Donor Interview & Verification 2

Question 1

Which of the following substances detected on a DOT drug test could result in a verified negative if the donor presents a valid current prescription?

Accepted Answer

Amphetamine

Answer

Amphetamines have legitimate prescription uses (e.g., Adderall, Vyvanse) and a valid prescription can support a verified negative report; cocaine, PCP, and marijuana metabolites have no accepted prescription context in DOT federal testing.

Question 2

Under DOT regulations, when a donor claims a prescription during the MRO interview but cannot immediately produce documentation, the MRO should:

Accepted Answer

Allow a reasonable time (up to 5 business days) for the donor to provide documentation while independently verifying

Answer

Per 49 CFR §40.135, the MRO must allow the employee a reasonable opportunity to provide documentation and can also independently verify the prescription with the prescriber or pharmacy.

Question 3

A donor's specimen tests positive for opiates. The donor claims to have eaten a large amount of poppy seeds before the test. How should the MRO respond?

Accepted Answer

Evaluate whether the specific morphine concentration is consistent with poppy seed ingestion at the DOT cutoff level

Answer

At the DOT morphine cutoff of 2,000 ng/mL, normal poppy seed ingestion typically cannot produce concentrations at this level, so the MRO must evaluate the specific concentration against the claimed explanation.

Question 4

A donor presents a valid medical marijuana card issued by their state to explain a positive THC result on a DOT drug test. The MRO must:

Accepted Answer

Report a verified positive since federal DOT regulations do not recognize marijuana as having accepted medical use

Answer

Under federal DOT regulations, marijuana has no accepted medical use regardless of state law; the MRO must report a verified positive even when the donor holds a valid state-issued medical marijuana card.

Question 5

During verification of a positive opiate result, the donor reveals a valid prescription for oxycodone for chronic pain. What additional determination must the MRO make?

Accepted Answer

Whether the prescribing physician has determined the employee is medically qualified to perform safety-sensitive duties while taking the medication

Answer

The MRO must verify not only that the prescription is valid but also whether the treating physician has cleared the employee to safely perform safety-sensitive functions while on the medication.
