MRO Source Selection & Evaluation 2

Question 1

When an MRO receives a specimen from a laboratory, which HHS-certified laboratory characteristic is MOST critical to verify before accepting results?

Accepted Answer

Current HHS certification under 49 CFR Part 40

Answer

Only HHS-certified laboratories may perform DOT-regulated drug testing, and the MRO must confirm this certification is current before accepting results.

Question 2

A collector submits a specimen to a lab that lost its HHS certification two days prior to collection. What should the MRO do?

Accepted Answer

Cancel the test and require a recollection

Answer

If the laboratory was not HHS-certified at the time of testing, the result is invalid and the MRO must cancel the test.

Question 3

Which document confirms that a specific laboratory holds current HHS certification for federal workplace drug testing?

Accepted Answer

SAMHSA's published list of certified laboratories

Answer

SAMHSA publishes and regularly updates the official list of HHS-certified laboratories that MROs may use to verify certification status.

Question 4

An employer wants to use an on-site instant test device for DOT-mandated testing. What is the MRO's correct guidance?

Accepted Answer

Prohibit it; DOT requires HHS-certified lab testing

Answer

49 CFR Part 40 prohibits the use of instant or point-of-collection testing devices for DOT-regulated testing; only HHS-certified labs may be used.

Question 5

Which of the following is an acceptable reason for an MRO to reject a laboratory's reported result?

Accepted Answer

The laboratory is not listed on the current SAMHSA certified lab list

Answer

An uncertified laboratory renders the test invalid; ink color is not a disqualifying discrepancy under 49 CFR Part 40.
