Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair captures a comprehensive record of alcohol and drugs by encapsulating biomarkers within the strands of the hair as it grows. When obtained near the scalp, hair can offer a detection period of up to three months for alcohol and various drugs. Collecting hair is straightforward, relatively tamper-resistant, and convenient to transport.
A hair sample measuring 1.5 inches, consisting of around 200 strands (similar in thickness to a #2 pencil) nearest to the scalp, provides 100mg of hair - the optimal amount for screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is suggested. Utilizing a jeweler’s scale is recommended for weighing the specimen. If scalp hair is not available, a comparable quantity of body hair may be used. When “head hair†is mentioned, it specifically refers to scalp hair. “Body hair†includes all other hair types (facial, axillary, etc.).
Process Overview
The essential stages in the laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample into the lab system, ensuring that it was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening provides an initial rapid assessment for substances of abuse. Although Screening is a cost-efficient method for eliminating drug use in most samples, a positive indication requires confirmation for legal admissibility. Any samples showing tentative positive results in Screening must undergo additional confirmation.
When a sample shows a tentative positive in the Screening phase, more hair is taken from the initial sample for Extraction. In this phase, drugs are extracted from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.
Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing tentative positive results are washed before confirmation, if necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
