§40.36 — What information about the DER must employers provide to collectors? As an employer, you must provide to collectors the name and telephone number of the appropriate DER (and C/TPA, where applicable) to contact about any problems or issues that may arise during the testing process.
§40.36 — DOT Regulatory Guidance
Question 1: How should the employer's decision to have a C/TPA act as intermediary in the handling of drug test results be documented? Guidance: 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.
