DOT Rule 49 CFR Part 40 Section 40.345 Q&A

• When an employer chooses to use the C/TPA as the intermediary in the transmission of the MRO’s verified drug test results, this decision should be communicated from the employer to the MRO and the C/TPA.

 

• We advise the MRO to obtain some documentation of the employer’s decision prior to sending results through the C/TPA.

 

• Documentation could be in the form of a letter, an email, or record of a telephone conversation with the employer.

 

• DOT also recommends that MROs maintain listings of the names, addresses, and phone numbers of C/TPA points of contact.
