Cocaine and Metabolite
Interpretation
- The presence of cocaine >LOQ indicates exposure to cocaine within 1 day prior to specimen collection.
- The presence of benzoylecgonine >LOQ indicates exposure to cocaine within 5 days prior to specimen collection.
Metabolites
- Cocaine is metabolized to several inactive metabolites, the predominant one being benzoylecgonine.
Cocaine → Benzoylecgonine
Confirmation Tests:
Approximate Detection Times
| Cocaine & Metabolite | LOQ (ng/mL) | Detection Time* up to |
|---|---|---|
| Cocaine | 50 | <1 day |
| Benzoylecgonine | 50 | 5 days |
*These are approximate detection times for the drug or metabolites in urine. The actual detection time depends on dose, frequency of
use, and individual metabolism.
