Hair analysis has become recognized as a robust technique for identifying drug and alcohol usage. Hair captures a long-term record of substances by embedding biomarkers within the strands as they grow. When hair is gathered from near the scalp, it can offer a detection timeline of up to about three months for substances. Hair collection is straightforward, moderately tamper-resistant, and easy for transportation.
A specimen of about 1.5 inches consisting of 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp equates to 100mg, which is the optimal amount for both initial testing and verification. For EtG, supplementary assessments, and/or more extensive tests exceeding 10 panels, a 150mg sample is advisable. We suggest utilizing a jeweler’s scale for measuring the sample. If head hair is insufficient, a similar quantity of body hair may be used. By head hair, we specifically mean scalp hair, whereas body hair includes all other types such as facial or axillary.
Process Overview
The drug testing laboratory workflow includes four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial entry of a sample into the lab system. It involves checking whether the sample was properly sealed and sent, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data input if absent from an electronic chain of custody interface.
Screening performs an expeditious preliminary test for illegal drugs. While Screening offers a cost-efficient way to exempt samples of drug use, any positive Screening result necessitates validation for legal acceptability. Samples that are initially marked positive in Screening must undergo further confirmation.
If a sample registers a presumptive positive during Screening, additional hair from the original batch is extracted for the Extraction stage. Here, drugs are removed at an extremely low concentration, contrasting with other tests (ex. urine or saliva), making hair drug tests particularly challenging to execute.
Verification of any positive Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if needed. Every step from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair criteria and accreditation under ISO / IEC 17025 standards.
