This panel is useful for confirmation of screen positive results. Cocaine is metabolized mainly to benzoylecgonine and ecgonine. Cocaethylene is an indication of concurrent cocaine and alcohol consumption. Serum half-life of cocaine is 1-5 hours. Benzoylecgonine appears in circulation 15-30 minutes after cocaine administration. Elimation half-life of benzoylecgonine is 5-6 hours. Benzoylecgonine will be detected in urine after 2-3 hours and urine remains positive for 2-3 days (longer for chronic abusers) after cocaine use.
