  1. What is the role of the MRO when reviewing a confirmed positive test result?

    The MRO evaluates whether a legitimate medical explanation, such as a prescribed medication, exists before reporting the result.

  2. What is the next step if a donor claims a prescription for a detected substance?

    Answer: Verify the prescription source

    The MRO must verify the prescription with a pharmacy or prescribing physician to confirm legitimacy.

  3. What does a 'negative-dilute' result indicate?

    Answer: Diluted sample with no drugs

    A negative-dilute result means the sample was diluted but no drugs were detected; a retest may be required based on policy.

  4. Why must the MRO maintain confidentiality during review?

    Answer: To protect donor privacy and comply with law

    Maintaining confidentiality is critical to protect the donor's medical privacy and comply with legal standards.

  5. How does the MRO notify an employee of a positive result?

    Answer: Attempt confidential contact with the donor

    The MRO must make a reasonable effort to contact the donor confidentially before final reporting.

  6. What does a verified negative result mean?

    Answer: No drugs detected and specimen was valid

    A verified negative result indicates no prohibited substances were found and the sample met validity standards.
