Confirmatory exams in toxicology are advanced analytical procedures used to verify the presence of specific toxins, drugs, or chemicals in biological samples. These exams are crucial in clinical, forensic, and environmental toxicology to provide definitive results that are admissible in legal and medical contexts. Unlike initial screening tests, which might be prone to false positives or negatives, confirmatory exams provide high specificity and accuracy, ensuring that the identified substance is present and correctly quantified.
