Hair analysis has become recognized as a robust method for identifying drug and alcohol consumption. Hair strands offer an extended timeline of substance usage by encapsulating biomarkers within the strand's fibers. When hair is collected near the scalp, it can offer detection for up to roughly three months for alcohol and other drugs. Collecting hair is straightforward, relatively tamper-proof, and easy to send.
A 1.5-inch hair sample consisting of approximately 200 strands (the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample size for testing and validation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair cannot be collected, an equivalent quantity of body hair may be taken. When mentioning head hair, we refer specifically to scalp hair. Body hair includes any other types, like facial or axillary hair.
Process Overview
The laboratory processing of a drug test result primarily includes four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of incorporating a sample into the lab's workflow. This step ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and fills in any lacking data not covered by an electronic chain of custody system.
Screening is an initial rapid assessment for drugs of abuse. Screening is a cost-efficient way to rule out drug consumption in most samples, but a positive result in Screening requires confirmation to be valid in legal proceedings. Samples with presumptive positive results in Screening need an additional confirmation step.
If a sample appears presumptively positive during Screening, more hair is taken from the initial sample and readied for Extraction. In Extraction, drugs are removed from hair at a much lower concentration than seen in other methods like urine or oral fluid. This characteristic makes hair drug testing the most challenging methodology to execute.
Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo a washing process before confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized by both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
