Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. By encasing biomarkers in the strands of growing hair, it delivers a prolonged record of alcohol and drug usage. When clipped near the scalp, hair can reveal substance use over roughly a 3-month timeframe. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch portion of approximately 200 hair strands (akin to the girth of a #2 pencil) near the scalp weighs 100mg, which is the preferred quantity for tests and confirmations. For EtG, additional testing, or analyses beyond 10 panels, 150mg is advised. Utilizing a jeweler's scale to weigh the sample is recommended. If scalp hair is unavailable, a similar amount of body hair may be utilized. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (including facial, axillary, etc.).
Process Overview
The core procedures in the lab analysis of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample into a laboratory's framework. This step entails checking that the sample was correctly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry not already conducted by an electronic chain of custody system.
Screening offers a preliminary assessment for illicit substances. Though Screening is an economical method to eliminate drug consumption in most samples, a positive result must undergo confirmation for legal admissibility. Any samples with presumptive positive results require subsequent confirmation.
If a sample shows presumptive positivity during Screening, additional hair is retrieved from the original sample and readied for Extraction. In this phase, substances are removed from hair at substantially lower levels than in other techniques (such as urine or oral fluid), which is why hair analysis is among the most challenging modes to execute.
Confirmation of any positive screen result is administered using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are pre-washed before confirmation as necessary. The entire lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation along with the accreditation to ISO / IEC 17025 standards.
