A highly sensitive and specific test that can be used as legal evidence is best described as a:

The main idea is that a test used as legal evidence must uniquely identify a substance with very high accuracy. A definitive test achieves this by using precise, instrument-based methods (such as GC-MS or LC-MS/MS) that provide both high sensitivity and high specificity. This combination minimizes false positives and false negatives, producing results that are reliable enough to stand up in court or regulatory proceedings. Presumptive tests are useful for quick screening, but their results can be misleading due to cross-reactivity or lack of specificity, so they’re not sufficient on their own for legal evidence. Waived tests refer to simple, low-complexity assays under CLIA, not inherently tied to evidentiary strength. Non-waived tests are more complex, but the key factor for legal admissibility is whether the method is definitive—confirmatory and highly trustworthy—which is why the correct description is a definitive test.
