Hair analysis is recognized as a robust method for identifying substance and alcohol consumption. Hair can chronicle an extensive history of substance use by encapsulating biomarkers within the fiber of a growing strand. When clipped near the scalp, hair can reveal a usage pattern for alcohol and other substances for approximately up to three months. Hair is straightforward to gather, relatively tamper-proof, and convenient to transport.
A sample measuring 1.5 inches containing roughly 200 hairs (comparable to the thickness of a #2 pencil) close to the scalp yields 100mg, which is optimal for initial and confirmatory testing. For EtG evaluations, additional analyses, or tests exceeding ten panels, 150mg of hair is suggested. Utilizing a jeweler’s scale is advised for weighing the sample. Should scalp hair not be available, an equivalent quantity of body hair can suffice. When mentioning head hair, it refers exclusively to scalp hair, whereas body hair encompasses all alternatives such as facial and axillary hair.
Process Overview
Drug testing in the lab involves four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory phase where a sample is integrated into the lab's system. This entails ensuring the sample’s secure packaging and dispatch, generating a random LAN (Laboratory Accessioning Number), and fulfilling any outstanding data entry not managed by an electronic chain of custody system.
Screening is concerned with an early-stage rapid assessment for substances. Although cost-efficient for excluding drug use in most samples, a positive result must undergo Confirmation to be used legally. Samples that exhibit presumptive positives in Screening require follow-up Confirmation.
In cases where a sample shows presumptive positivity in Screening, additional hair is extracted from the primary sample and prepared for Extraction. In this process, drugs are extracted from hair at concentrations significantly lower than other methods (such as urine or oral fluid), making hair testing one of the most challenging techniques.
Positive screenings are validated through GC/MS, GC/MS/MS, or LC/MS/MS methods. Each presumptively positive sample is cleansed before Confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
