Hair examination is recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of substance use by capturing biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can reveal up to about a three-month identification span for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section comprising roughly 200 hair strands, similar in size to a #2 pencil, near the scalp will yield 100mg of hair, the optimal sample for both screening and verification. For EtG, supplementary tests, and/or analyses beyond 10 panels, it is advisable to use 150mg of the hair sample. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair is not obtainable, an equivalent quantity of body hair can be utilized. When referring to head hair, it specifically means scalp hair only, whereas body hair encompasses other types (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the primary processing of a sample into the lab’s system. This process includes checking that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finishing any further data input that is absent in an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of misuse. Screening serves as a budget-friendly approach to exclude drug use in the majority of samples; however, a positive screen necessitates confirmation for legal acceptance. Samples showing presumptive positivity in Screening need further confirmation.
If the Screening phase yields a presumptive positive result, additional hair is taken from the initial sample for preparation in the Extraction phase. Drugs are extracted in this phase from hair at a lower concentration than in alternative methodologies (e.g., urine or oral fluid), rendering hair drug screening the most complex method to perform.
Confirming any positive screening outcome is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.
