Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair encases a chronological record of alcohol and other drugs by embedding biomarkers within the strands. When collected near the scalp, it offers a detection period for alcohol and other substances extending to roughly three months. Hair is straightforward to gather, relatively challenging to tamper with, and convenient to dispatch.
A 1.5-inch sample comprising around 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp is sufficient to yield 100mg of hair, representing the perfect sample size for analysis. For EtG, additional screenings, or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be used. By head hair, we denote exclusively scalp hair. Body hair pertains to any other hair forms (facial, axillary, etc.).
Process Overview
The laboratory workflow of processing a drug test outcome encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary procedure of incorporating a sample into a lab’s framework. This step includes confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry absent from an electronic chain of custody system.
Screening signifies an initial rapid evaluation for drugs of abuse. Although Screening is an economical approach to exclude drug usage in most samples, a positive screening necessitates confirmation for court acceptance. Any samples with presumed positive results during Screening require additional verification.
In cases where Screening indicates a presumptive positive, more hair is extracted from the original sample for the Extraction phase. At this phase, drugs are liberated from hair at a significantly lower concentration than other methods (such as urine or oral fluid), underscoring why hair drug screening poses the most intricate method to execute.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation when needed. The entire lab procedure from Accessioning to Confirmation is scrutinized beneath both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
