Hair testing is recognized as a valuable method for identifying drug and alcohol consumption. Hair strands record long-term evidence of alcohol and drug use by encasing biomarkers within their fibers. When obtained from near the scalp, hair offers around a 3-month detection period for substances. Hair is easy to gather, relatively tamper-resistant, and convenient to transport.
A 1.5-inch segment of about 200 hair strands (roughly pencil-sized) nearest to the scalp yields 100mg, the optimal amount for testing and verification. For EtG, additions, and/or tests over 10 panels, 150mg of hair is advisable. We suggest using a jeweler's scale to weigh the specimen. If scalp hair is not available, an equivalent volume of body hair could be used. Head hair denotes only scalp hair, while body hair covers all other hair types (such as facial, axillary, etc.).
Process Overview
The drug test result in a laboratory is divided into four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing stage where a sample is incorporated into a laboratory’s system. It involves ensuring the sample is sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and inputting any missing information not captured by an electronic chain of custody system.
Screening serves as an initial rapid examination for drug abuse. This cost-efficient step helps eliminate drug usage for most samples, yet any positive reads need confirmation for legal acceptance. Samples testing presumptive in Screening do require further verification.
If a sample appears positive during Screening, additional hair is extracted from the initial sample and set up for Extraction. This stage separates drugs from hair at significantly lower concentrations compared to other approaches (such as urine or oral fluid), making hair drug testing the most challenging technique to execute.
Positive screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive samples receive a wash before confirmation if necessary. The full process from Accessioning to Confirmation undergoes reviews under CAP (College of American Pathologists) Hair standards and conforms to ISO / IEC 17025 standards.
