Hair analysis is increasingly regarded as an effective means for identifying the consumption of alcohol and drugs. Hair preserves a prolonged timeline of substance use by capturing biomarkers within its fibers as it grows. Hair samples collected near the scalp offer a detection window of up to roughly 3 months for various substances. The process of hair collection is straightforward, manipulation is challenging, and shipping is uncomplicated.
A sample measuring 1.5 inches, consisting of around 200 hair strands (similar in size to a standard pencil), ideally provides 100mg, optimal for both screening and confirmation. For tests involving EtG, additional screenings, or panels exceeding 10, a specimen weighing 150mg is advisable. It is suggested to use a jeweler’s scale for precise measurement. If head hair is unavailable, a similar quantity of body hair can be utilized. 'Head hair' specifies only scalp hair, whereas 'body hair' means any non-scalp hair (such as facial or underarm hair).
Process Overview
The core phases in laboratory processing for drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails entering a specimen into the laboratory system, checking for proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody.
Screening provides a preliminary check for substance abuse. Though cost-effective to exclude drug usage in most cases, any positive results necessitate confirmation for legal admissibility. Samples showing presumptive positives in Screening need additional verification.
If Screening yields a presumptive positive, additional hair is sourced from the original sample for the Extraction. Here, the drugs are extracted at lower concentrations than other methods (such as urine or saliva), making hair screening more challenging.
Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are cleansed before Confirmation when necessary. The complete process, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair standards as well as the ISO / IEC 17025 accreditation.
