Hair analysis is increasingly recognized as an effective means for detecting substance and alcohol consumption. Hair captures a lengthy record of alcohol and drug intake by embedding biomarkers within the structure of the maturing hair strand. When samples are taken near the scalp, hair can reveal a detection period of up to approximately three months for substances and alcohol. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A segment of 1.5-inch hair comprised of approximately 200 strands (roughly the diameter of a #2 pencil) closest to the scalp yields 100mg, which is the optimal amount for initial testing and verification. For EtG, supplementary tests, or panels beyond 10, a 150mg sample is advised. The sample should be weighed using a jeweler’s scale. If scalp hair cannot be obtained, a comparable quantity of body hair may be used. When discussing head hair, it exclusively refers to scalp hair. Body hair encompasses all other types, such as beard, underarm, etc.
Process Overview
The key phases in the lab processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the preliminary handling of a specimen into a lab's database. This step ensures that the sample was properly sealed and transported, allocates a unique LAN (Laboratory Accessioning Number), and concludes any outstanding data entry not furnished by an electronic chain of custody framework.
Screening serves as an initial preliminary analysis for drug abuse substances. Though it's a cost-effective method to exclude drug use in most samples, a positive screen necessitates confirmation to be legally valid. Each sample that tests tentatively positive during Screening must undergo a subsequent confirmation.
In instances where a sample tests tentatively positive in Screening, additional hair is extracted from the primary specimen for the Extraction phase. This phase involves extracting drugs from hair at significantly lower concentrations compared to other tests (e.g., urine or saliva), which underscores the complexity of hair drug screening as a methodology.
Positive results from screenings are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples that are tentatively positive are washed as required. The entire lab process from Accessioning through to Confirmation is audited in line with the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 accreditation standards.
