In laboratory terminology, a method with documented accuracy and precision is referred to as what?

• A. Reference
• B. Gold Standard
• C. Presumptive
• D. Confirmatory

Answer: (A)

When a method has documented accuracy and precision, it is described as a reference method. This means its performance characteristics—how close results are to the true value (accuracy) and how consistently they can be reproduced (precision)—have been formally validated and recorded. A reference method serves as a benchmark against which other assays are measured, providing a standard for calibration, quality control, and comparison across labs. It is typically linked to reference materials and quality programs to ensure results are traceable and reliable. While terms like gold standard are often used more loosely to denote the best available method, the precise laboratory terminology for a validated, benchmark method is reference method. Presumptive tests give initial indications, and confirmatory tests verify results, but they do not by themselves define a validated benchmark.
