The recognition of hair testing is growing as a highly effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of alcohol and drug usage by embedding biomarkers within the structure of the growing hair strand. When collected near the scalp, hair can reveal up to a three-month detection period for alcohol and drugs. The process of collecting hair is straightforward, harder to tamper with, and easy to transport.
A sample of approximately 200 strands (equivalent to a #2 pencil) measuring 1.5 inches closest to the scalp produces 100mg of hair, which is the optimal amount for initial screening and verification. For EtG, supplementary tests, or those beyond 10 panels, it is advisable to collect 150mg. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair may be gathered. References to head hair specifically denote scalp hair. Body hair includes all other types (e.g., facial, axillary).
Process Overview
The key phases in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial intake of a sample into the lab system. This stage involves confirming that the sample was sealed and shipped correctly, assigning a Laboratory Accessioning Number (LAN), and completing any necessary additional data entry not covered by a digital chain of custody system.
Screening entails a preliminary assessment to identify drugs of abuse. Though Screening is a cost-efficient means to exclude drug use in most samples, a positive result requires confirmation to be legally valid. Samples showing presumptive positive results in Screening need secondary confirmation.
Should a sample test presumptively positive at the Screening phase, additional hair is taken from the primary specimen and prepared for Extraction. During this step, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine, oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive results found during Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and compliance with ISO / IEC 17025 standards.
