   Target; PCP

   Limit of quantitation: 25 ng/mL [urine]; 2–10 ng/mL [blood/serum]

   Little to no cross-reactivity with PCP metabolites and varying cross- reactivity (20–90%) with PCP analogs [e.g., TCP-1-(1-thiophenecyclohexyl) piperidine]

   May cross react with dextromethorphan

   LSD

   Target:
D

   Limit of quantitation: 0.5 ng/mL

   Low (<20%) cross-reactivity with metabolites, no cross-reactivity with lysergic acid

   
Confirmation:
chromatography based; sample pretreatment/extraction procedure often required
