Result-Terms Summary
- What this covers: dilute, invalid, and substituted result terms in a federal DOT example.
- What it cannot do: predict your result, an employer decision, or whether a product will change either one.
- Best next step: read the written policy that applies to your test and ask the collector or medical-review contact how to interpret a reported status.
A product claim is not a laboratory result
If a test affects a job or program, do not ask which product can guarantee a pass. No product can promise a lab result or a later decision.
This guide compares marketing with result terms in one federal DOT example. It explains why a sample change is not a shortcut. It does not set rules for every test.
What “dilute” means in the DOT example
DOT has rules for dilute urine. They use creatinine and specific gravity. The source lists exact ranges.
In plain language, this is a lab status. It does not prove that a product worked. It does not prove that a person did something wrong. Programs can use different steps.
Invalid and substituted are not interchangeable
DOT uses a separate rule for a substituted sample. It uses repeat lab checks. For an invalid result, the rule says the lab must report the reason.
That difference matters. A sales page that treats all odd results as the same result leaves out key facts.
What the federal process shows—and what it does not
In the DOT process, an invalid result can mean another observed collection. This rule applies to federal transport testing. It does not forecast every job or program.
We cannot tell you what your test will show. We cannot tell you what a decision-maker will do. Read the policy you were given. Use the official contact in that policy for case-specific questions.
Five questions to ask before trusting a detox claim
- Does the seller promise a result instead of describing a verifiable product fact?
- Does it explain the limits of the claim, including the type of test and the program policy?
- Does it suggest changing or replacing a sample? If so, do not treat it as reliable test guidance.
- Can you find current terms, a return policy, and a way to contact the seller in writing?
- Have you checked the written policy that actually applies to your test?
