The utilization of hair analysis has emerged as an effective means for identifying the presence of substances, including narcotics and alcohol. Hair captures a chronological account of substance exposure by embedding chemical indicators within its growing fibers. When gathered near the scalp, hair can indicate substance use over a span of roughly three months. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches composed of around 200 hairs (comparable in size to a #2 pencil) nearest to the scalp delivers 100mg, the optimal amount for both initial and confirmatory analysis. For EtG, added tests, and screenings exceeding 10 substances, 150mg of hair is preferable. It is advisable to use a jeweler’s scale to weigh the sample. Should head hair be inaccessible, a similar quantity of body hair is acceptable. References to head hair are specific to scalp hair, while body hair encompasses all other varieties (e.g., facial, axillary).
Process Overview
The sequence for processing lab results for drug analysis involves: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary handling of a specimen within a lab setup. This step ensures the specimen was sealed and transported correctly, involves assigning a unique LAN (Laboratory Accessioning Number), and finalizes any data entry absent from an electronic custodial record.
Screening constitutes an initial rapid assessment for illicit substances. While Screening is an economical approach for dismissing drug presence in most samples, legal validation requires a positive screen to be substantiated. Samples showing presumptive positivity during Screening necessitate further confirmation.
For samples with preliminary positivity, additional hair is extracted from the initial batch and readied for Extraction. During Extraction, drugs are isolated from hair at significantly reduced concentrations compared to other analyses (such as urine or saliva), hence why hair drug analysis is notably complex.
Confirmation of Screening-positive findings is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Each selected positive sample undergoes cleansing prior to confirmation as required. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and in line with ISO / IEC 17025 accreditation.
