Ketamine
Interpretation
- The presence of ketamine or norketamine >LOQ indicates exposure to ketamine within 2 days.
Metabolites
- Ketamine is metabolized by N-demethylation to the active metabolite norketamine.
Ketamine → Norketamine
Confirmation Tests:
Approximate Detection Times
| Ketamine | LOQ (ng/mL) | Detection Time* up to |
|---|---|---|
| Ketamine | 25 | 2 days |
| Norketamine | 25 | 2 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.
