Hair analysis is increasingly recognized as an effective means to identify drug and alcohol consumption. Hair captures a long-term record of drug and alcohol presence by embedding biomarkers within the hair strand fibers as they grow. A sample taken close to the scalp can reveal drug and alcohol usage for a duration of up to about three months. Collecting hair is straightforward, less prone to tampering, and convenient for transport.
A 1.5-inch length of approximately 200 hair strands, roughly the diameter of a #2 pencil, cut closest to the scalp, generates 100mg of hair, which is optimal for initial screening and verification. For EtG, additional testing, and/or assessments beyond ten panels, 150mg of hair is advisable. We suggest using a jeweler's scale for precision in weighing the sample. When scalp hair is unobtainable, an equivalent volume of body hair can be substituted. Head hair refers specifically to scalp hair, while body hair includes all other types (like facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome consists of four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the introduction of a sample into a lab's framework. This step involves ensuring that the sample was sealed and transported correctly, generating a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic chain of custody system.
Screening serves as an initial rapid assessment for drug presence. Although Screening is economical for initially excluding drug use in most samples, a positive result must be confirmed for legal acceptability. Any samples that test presumptively positive during Screening necessitate further confirmation.
When a sample shows a presumptive positive result in the Screening stage, additional hair from the original collection is utilized for Extraction. During this process, drugs are isolated from hair at concentrations much lower than in other methods (e.g., urine or oral fluid), which explains why hair drug testing presents the most significant challenge in methodology.
Confirmed positive results from Screening undergo verification using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples are cleansed before confirmation when necessary. The complete lab procedure from Accessioning to Confirmation adheres to the guidelines set by both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
