AI Adulterated Specimen Investigation Playbook

A laboratory reported a specimen as adulterated with glutaraldehyde for a DOT-regulated airline employee. The donor denies any tampering. The MRO must determine whether to report this as a refusal to test. The donor is a 15-year employee with no prior test history and a clean safety record.

When to use this playbook

• Use this playbook when the decision looks like the situation above: A laboratory reported a specimen as adulterated with glutaraldehyde for a DOT-regulated airline employee.
• It is a fit when you have source files in hand and need a structured, reviewable analysis — not a generic chat answer about "Adulterated Specimen Investigation".
• Do not use it as a substitute for licensed, legal, clinical, or authorized official judgment in the domain.

What you'll need

• Laboratory adulteration report (glutaraldehyde detection and confirmatory test results)
• DOT 49 CFR Part 40 adulterated specimen provisions
• Donor interview notes (denial of tampering)
• Employee work history and prior drug test record
• FAA return-to-duty and safety-sensitive requirements

You are a Medical Review Officer adjudicating an adulterated specimen result for a DOT-regulated airline employee. I am attaching:

Work only from the attached source files. If a conclusion is not supported, say so.

Produce:
1. Assess the laboratory's adulteration finding: what is the scientific basis for the glutaraldehyde finding, and is there any endogenous explanation?
2. Review DOT 49 CFR Part 40: is an adulterated specimen automatically a refusal to test, or does the MRO have discretion based on the interview?
3. Assess the donor interview: under DOT rules, what can the MRO consider from the donor's explanation, and what is inadmissible?
4. Determine whether the employee's 15-year clean record has any bearing on the MRO's required determination.
5. Tell me the MRO's required reporting action, the exact regulatory language, and what the donor's appeal rights are.

Call out where independent models are likely to disagree, and list follow-up documents a reviewer should request.

What to expect

• Glutaraldehyde scientific basis and endogenous explanation assessment
• Refusal-to-test determination framework
• Donor interview admissibility analysis
• Prior record relevance to MRO determination
• Required reporting action with regulatory citation and appeal rights

Review before you act

• Confirm every cited figure, date, counterparty, or requirement against the attached originals — models compress and can drop a qualifier.
• Treat disagreement between models as a review item, especially on classification, materiality, and recommended next action.
• Do not authorize an operational, clinical, legal, credit, or enforcement action solely because the models agree.
