The assessment of drug and alcohol consumption through hair testing is recognized as an effective technique. Hair encapsulates a chronological record of substances by embedding biomarkers in the hair's growth fibers. When gathered near the head, hair can furnish a detection range of nearly three months for various substances, including alcohol. The process of hair collection is straightforward, relatively resistant to tampering, and convenient for transportation.
Taking a 1.5-inch segment from around 200 hair strands (similar in thickness to a #2 pencil), positioned nearest to the head, yields 100mg of hair, which is the ideal amount for testing purposes. When dealing with EtG, additional tests, or more comprehensive screenings above 10 panels, a specimen of 150mg is advocated. It's advisable to measure the sample on a jeweler’s scale for accuracy. In the absence of scalp hair, a comparable quantity of body hair could be utilized. It's important to specify when referring to head hair, it means scalp hair exclusively. Conversely, body hair encompasses all other hair classifications (like facial or underarm hair).
Process Overview
The drug test result processing at the laboratory comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial integration into the laboratory's system. This phase ensures the sample is securely sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any outstanding data entry absent from an electronic chain of custody system.
Screening is a preliminary fast examination for illicit substances. Although Screening is a cost-efficient method to exclude drug intake in most samples, any positive findings necessitate confirmation for them to hold up legally. Presumptive positives in Screening must undergo secondary validation.
If the Screening phase indicates a presumptive positive, additional hair is extracted from the original sample for Extraction. In this phase, substances are isolated from hair in concentrations substantially lower than other techniques (such as urine or oral fluids), marking hair drug screening as the most challenging method to conduct.
Verification of any positive findings in Screening is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples flagged as presumptive positives are cleansed as required. The comprehensive lab process, from Accessioning to Confirmation, undergoes evaluation under the CAP (College of American Pathologists) Hair designation in addition to ISO / IEC 17025 accreditation standards.
