Hair examinations are recognized as an effective means for spotting drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers within the hair strand's fibers. By obtaining samples near the scalp, one can determine alcohol and drug use history spanning up to roughly three months. Collecting hair is straightforward, relatively tamper-resistant, and simple to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp provides 100mg, which is optimal for both preliminary and confirmatory testing. For EtG, supplemental testing, or panels above ten, 150mg of the sample is suggested. It's advisable to use a jeweler’s scale for weighing. If scalp hair isn't available, an equivalent amount of body hair may be collected. Head hair specifically refers to scalp hair, while body hair encompasses any other types (e.g., facial, axillary).
Process Overview
Drug test results are processed in the lab through four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of entering a sample into a lab's system. It involves ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and inputting any extra data absent from an electronic chain of custody system.
Screening provides a preliminary check for drug misuse. Although cost-effective for ruling out drug use in most samples, a positive screen must be validated for legal admissibility. Samples showing presumptive positives during Screening require secondary validation.
Should a sample show a presumptive positive during Screening, additional hair is extracted for further analysis. In this phase, drugs are extracted from hair at concentrations significantly lower than those in other methods such as urine or oral fluid, making hair drug testing particularly challenging to execute.
A confirmed positive from screening is further analyzed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive are cleansed before confirmation as needed. This comprehensive lab process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation, alongside the ISO / IEC 17025 accreditation standards.
