High Specificity for Fentanyl
Reduce False Positives: Assays that do not cross-react with norfentanyl ensure that positive results are specifically due to the presence of fentanyl, not its metabolites. This is crucial for accurately identifying current fentanyl use rather than past use.
Improve Monitoring: Specific assays help distinguish between recent fentanyl administration and the presence of residual metabolites from earlier use, aiding in more precise interpretations.
Low Cross Reactivity with the Major Urinary Metabolite Norfentanyl
