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

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.
