This study evaluates the correlation between portable on-site testing devices and laboratory-based analyses for food, drug, and toxicology samples. Portable devices offer rapid preliminary results, while laboratory tests provide high-precision confirmation. By comparing sensitivity, specificity, detection limits, and accuracy, the study demonstrates the reliability of field devices and identifies best practices for sample handling, result interpretation, and follow-up testing. The findings guide regulatory agencies, law enforcement, and quality control teams in optimizing workflows, improving efficiency, and ensuring accurate decision-making in both field and lab environments.
