Understanding Lab Tests for Cocaine Use
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Cocaine use detection relies on laboratory testing that can identify the presence of cocaine and its metabolites in the body. Blood testing provides a reliable method for confirming recent cocaine use, typically within a specific detection window.
Recommended Test
Cocaine and Metabolites, Confirmation, Serum, Plasma, or Blood
This comprehensive test detects both cocaine and its primary metabolite, benzoylecgonine, in blood samples. Cocaine itself is detectable for a few hours to 1-2 days after use, while benzoylecgonine, the primary metabolite, can be detected for 1-2 days after cocaine use. The presence of either substance provides confirmation of recent cocaine use.

How Cocaine Detection Testing Works
When cocaine is consumed, the body metabolizes it into various compounds, including benzoylecgonine, which is the primary metabolite. Blood tests can detect both the parent drug (cocaine) and its metabolites, providing evidence of recent use within a defined timeframe.
Detection Timeframes
The detection window for cocaine in blood is relatively short compared to other testing methods. Cocaine itself may be detectable for several hours to 1-2 days, while its metabolites can extend the detection period to 1-2 days after last use. The exact timeframe can vary based on factors such as frequency of use, metabolism, and individual physiology.
