How Do Confirmatory Exams Differ from Screening Tests?
Screening tests are preliminary tests designed to quickly identify the possibility of a substance being present. They are generally faster and less expensive but may lack the specificity of confirmatory tests. Confirmatory exams, on the other hand, are more comprehensive and detailed, often requiring more time and resources. While screening tests might use methods like immunoassays, confirmatory exams rely on highly sophisticated instrumentation and techniques to provide a definitive analysis.
