Invalid samples constitute one of the most frequently encountered error messages generated during routine breath alcohol testing, yet are the error conditions most frequently mis-managed by breath test operators, often with devastating consequences for your client. Seriously, this article (and the one on Deficient Samples) should be considered part of your core curriculum in breath alcohol testing.
