Ethanol and Cocaethylene in Hair (24-Hour Quantification)

What Does This Test Measure?

Hair testing analyzes small amounts of substances trapped in your hair follicles. Ethanol and cocaethylene are detected through specialized laboratory methods that identify their chemical signatures in hair strands. This method is particularly useful for detecting prolonged substance exposure that may not be captured by urine tests.

Why Might Your Doctor Order This Test?

Your healthcare provider may recommend this test if they suspect long-term substance use, such as chronic alcohol or cocaine exposure, or if you’re part of a program monitoring substance use over time. It can also be used in workplace safety assessments or legal cases requiring evidence of prolonged substance use.

How Is This Test Performed?

A small sample of hair is collected, usually from the scalp or other areas. The hair is processed in a lab where advanced techniques, such as mass spectrometry or chromatography, break down the hair into components to detect ethanol and cocaethylene. Results are reported as concentrations of these substances in the hair.

What Do the Results Mean?

Results indicate the presence and relative amount of ethanol and cocaethylene in your hair. Positive results suggest recent or ongoing exposure to alcohol and cocaine, but interpretation depends on the concentration levels and clinical context. Consult your doctor for guidance on what these findings may imply for your health or situation.
