Hair analysis has become recognized as a potent method for identifying drug and alcohol consumption. Hair encapsulates a prolonged track record of alcohol and other substances by imprisoning biomarkers within the fiber strands of hair as it grows. When collected near the scalp, hair can offer a detection span of up to roughly three months for alcohol and other substances. It is straightforward to gather, relatively challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for analysis and verification. For EtG, add-ons, and/or evaluations exceeding 10 panels, a specimen of 150mg is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. Should scalp hair be unavailable, an equivalent quantity of body hair is acceptable. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four essential steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a specimen within a lab’s system. This step ensures the sample is appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and concludes any other data input missing from an electronic chain of custody process.
Screening involves a preliminary swift analysis for drugs of interest. Although Screening is an economical means to eliminate drug use in most samples, a positive outcome necessitates confirmation to be court-admissible. Any samples that show a presumptively positive result in Screening demand further validation.
If a sample displays a presumptively positive outcome in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this step, drugs are extracted at a concentration significantly lower than in other methodologies (e.g., urine or oral fluid), making hair drug testing the most complex methodology to conduct.
Confirmation of any positive Screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positives are cleansed as necessary before confirmation. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
