The provided text describes three urine drug tests (Amphetamine, Secobarbital, and Oxazepam) but does not include any study data or acceptance criteria. The document is a 510(k) summary for a premarket notification to the FDA, demonstrating substantial equivalence to a predicate device. It defines the intended use and compares technological characteristics with a predicate device, but there is no information about analytical or clinical performance studies with acceptance criteria.

Therefore, I cannot provide the requested information regarding acceptance criteria, reported device performance, sample sizes for test/training sets, data provenance, expert details, adjudication methods, MRMC studies, standalone performance, or ground truth establishment based on the provided text.

The closest information available is the intended use and cut-off values, which are listed in the "Comparison to the predicate device" table ({1}). However, these are specifications, not acceptance criteria for performance.
