This blood test screens for cocaine by detecting its metabolites, chiefly benzoylecgonine. It uses an immunoassay, so a positive result is a presumptive finding. Blood is chosen when a clinician wants an indication of recent circulating cocaine exposure, since cocaine and its metabolites clear from blood much faster than they do from urine. The assay targets benzoylecgonine, so it is intended to reflect recent exposure rather than long-term history.

• Cocaine metabolite (benzoylecgonine) The primary metabolite formed after cocaine use, detected in blood as an indicator of recent exposure.

• A clinician needs to assess recent cocaine exposure using a blood sample.
• A medical setting requires rapid screening for cocaine metabolites.
• You are in a situation where blood is the required specimen type.
• Cocaine exposure is part of a broader clinical or toxicology evaluation.

• No fasting is required for this blood screen.
• Report all medications, including local anesthetics and stimulants.
• Tell the clinician about any recent medical procedures using numbing agents.
• Continue prescribed medications unless a healthcare provider advises otherwise.

A negative blood cocaine metabolite screen suggests benzoylecgonine was not detected above the cutoff at collection. Because cocaine metabolites leave blood quickly, a negative result does not exclude use on earlier days. A positive screen is presumptive and may be confirmed with a more specific method. Discuss the result and its context with a healthcare provider before drawing conclusions.
