Hair testing is recognized as an effective method for identifying drug and alcohol usage. It offers a detailed timeline of substance exposure by capturing biomarkers within the strands of developing hair. When hair near the scalp is sampled, it can reveal drug and alcohol use for up to about three months. Collecting hair is straightforward, challenging to tamper with, and easy to send for analysis.
Obtaining a 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is the optimal amount for both initial testing and validation. For EtG, additional testing, or screenings exceeding 10 panels, a sample size of 150mg is advised. It is recommended to weigh the sample using a jeweler's scale. In the absence of scalp hair, an equivalent amount of body hair may be used. The term "head hair" denotes only scalp hair, while "body hair" includes all other types (e.g., facial, underarm).
Process Summary
The laboratory procedures for processing a drug test result consist of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into the lab’s system. This stage involves confirming the sample’s proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and conducting any supplementary data input not automatically handled by an electronic custody tracking system.
Screening entails a preliminary check for drug presence. Although Screening is a cost-efficient method for excluding drug use in most samples, positive findings must be confirmed for legal validity. Samples testing positive in Screening need further confirmation steps.
When a Screening test is positive, additional hair is extracted from the original sample to undergo Extraction. Drugs are isolated from hair at lower concentrations than in other testing methods (such as urine or saliva), which is what makes hair drug testing particularly challenging.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation if necessary. The whole lab process from Accessioning to Confirmation is evaluated in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
