Hair analysis is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair stores a long-term record of substance use by embedding biomarkers within the strands as they grow. When clipped near the scalp, a hair sample can reveal alcohol and drug use over a period of up to roughly three months. The sampling of hair is straightforward, difficult to tamper with, and suitable for transport.
A sample of 1.5 inches from approximately 200 strands of hair (roughly the thickness of a #2 pencil) close to the scalp yields 100mg of hair, which is the preferred amount for both tests and confirmations. For EtG, additional tests, and those beyond 10 panels, a sample of 150mg is advised. It's recommended to use a jeweler’s scale for accurate measurement. If there isn’t enough scalp hair, then a corresponding amount of body hair may be taken. When "head hair" is mentioned, it refers exclusively to scalp hair, whereas "body hair" pertains to other types of hair (like facial or underarm hair).
Process Overview
There are four key phases in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a lab’s system. It includes confirming the sample's sealing and correct shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any other data entry that an electronic chain of custody system might lack.
Screening is a preliminary and rapid check for drug presence. While it is a cost-efficient method to dismiss drug use in most samples, a positive screen necessitates confirmation to be accepted in legal settings. Any samples with presumptive positives in Screening need subsequent verification.
For samples suspect in the Screening stage, additional hair is taken from the original specimen and readied for Extraction. Here, drugs are extracted from hair at concentrations significantly lower than in other methods (like urine or oral fluid), contributing to the complexity of hair drug analysis.
Confirmation of any positive result from the screening is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleaned appropriately before confirmation. The entire lab operation from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
