Hair testing is recognized as a potent resource for identifying drug and alcohol consumption. It entails a comprehensive timeline of alcohol and drug usage, as it captures biomarkers within the hair strand's growing fibers. A sample obtained near the scalp can offer a drug and alcohol detection timeframe of up to approximately three months. Hair collection is straightforward, reasonably tamper-resistant, and conveniently shippable.
A 1.5-inch section comprising around 200 hair strands (equivalent to a #2 pencil) from the scalp's proximity yields 100mg of hair, optimal for both screening and confirmation. In cases involving EtG, add-ons, or screenings exceeding 10 panels, a specimen of 150mg is advisable. It is recommended to determine the specimen's weight with a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be used. Head hair refers explicitly to scalp hair, whereas body hair encompasses all other hair types, including facial and axillary hair.
Process Overview
The processing of a drug test result in a lab comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning represents the preliminary phase where a sample is assimilated into a laboratory’s setup. This step involves ensuring that the sample is properly sealed and shipped, associating a random LAN (Laboratory Accessioning Number), and completing any remaining data input not covered by an e-chain of custody system.
Screening offers an initial assessment for substances of abuse. Although Screening is a cost-efficient strategy for dismissing drug usage in most cases, a confirmed positive screen is necessary for legal admissibility. Samples with a presumptive positive result in Screening mandate an additional confirmation step.
For samples testing positive in the Screening phase, additional hair may be sourced from the original specimen for Extraction. In this phase, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing a challenging procedure.
To confirm any positive screens, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are employed. Samples with presumptive positives undergo washing before confirmation, if needed. The complete lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
