Hair testing is recognized as a robust method for identifying alcohol and drug consumption. Hair captures biomarkers within the strands, offering a long-term record of substance use. Collected near the scalp, hair samples can reveal drug or alcohol presence for up to about three months. It is straightforward to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch section comprising roughly 200 hair strands (approximating the thickness of a #2 pencil) near the scalp provides 100mg of hair, ideal for tests. For EtG, additional analyses, and tests exceeding 10 panels, a 150mg sample is advised. Utilize a jeweler's scale for precision. If scalp hair is lacking, equivalent body hair may be used. "Head hair" pertains only to scalp hair, whereas "body hair" includes facial and axillary hair, among others.
Process Overview
The laboratory analysis of a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails initiating a sample into the lab’s system, ensuring proper seal and shipment, assigning a Laboratory Accessioning Number (LAN), and completing any needed data entry not covered by an electronic chain of custody system.
Screening provides an expedited assessment for drug presence. While cost-effective to largely exclude drug use, a positive screening result necessitates confirmation for legal acceptance. Any samples that test presumptively positive in Screening demand further confirmation.
Should a sample indicate presumptive positivity during Screening, additional hair is extracted from the initial batch for Extraction. This phase involves obtaining drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most intricate methodologically.
Confirmation of positive Screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples receive a wash prior to confirmation as necessary. The entire procedure from Accessioning to Confirmation undergoes scrutiny per CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 accreditation.
