The application of hair testing has emerged as a potent method for identifying the use of drugs and alcohol. Hair can encapsulate biomarkers within the growing fiber strands, offering a historical timeline of alcohol and other substances. When clipped close to the scalp, hair samples can offer approximately a 3-month window for detecting alcohol and drugs. Collection is straightforward, tampering is relatively challenging, and shipment is convenient.
Obtaining a 1.5-inch segment, approximately 200 hair strands (comparable to a #2 pencil's diameter) nearest to the scalp results in a 100mg sample, which is optimal for both screening and confirmation. For tests involving EtG, add-ons, or those exceeding 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale is recommended for weighting the specimen. If head hair is inaccessible, body hair of equal quantity may be used. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
The Accessioning phase entails the preliminary integration of a sample into the lab's system. This phase includes the verification of proper sample sealing and shipment, the allocation of a random LAN (Laboratory Accessioning Number), and the completion of any supplemental data entry absent from electronic chain-of-custody systems.
The Screening phase involves an expedient preliminary evaluation for drugs of abuse. Screening serves as a cost-efficient means to negate drug usage for the bulk of samples. However, any positive screen must undergo Confirmation to ensure admissibility in a legal context. Samples returning presumptive positive results in Screening are subject to further Confirmation.
Samples found presumptively positive during Screening advance to the Extraction stage, where additional hair is extracted from the initial collection for preparation. In this stage, drugs are drawn from hair at markedly lower concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples identified as presumptive positive undergo cleansing prior to Confirmation, as warranted. The complete lab process—from Accessioning to Confirmation—is scrutinized per both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
