Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. It offers a comprehensive record of substance use by embedding biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair delivers a detection range of roughly three months for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transportation.
Gathering a 1.5-inch sample consisting of approximately 200 hair strands (around the diameter of a #2 pencil) from the scalp yields 100mg of hair, which is optimal for analysis and verification. For tests involving EtG, supplementary measures, and/or exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for measurement is suggested. In instances where scalp hair isn't accessible, a comparable quantity of body hair can be collected. By head hair, we mean scalp hair only. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for evaluating a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary phase of integrating a sample into a lab's system. This step involves confirming the sample's proper sealing and transportation, generating a random LAN (Laboratory Accessioning Number), and addressing any additional data entry omitted by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for substance misuse. While Screening is economical for eliminating drug use in most samples, any positive indication requires confirmation to be legally valid. Samples preliminarily positive in Screening necessitate further confirmation.
Should a sample be preliminarily positive during Screening, more hair is taken from the initial collection and prepped for Extraction. At this juncture, substances are segregated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Verification of any positive screening outcome is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Required presumptive positive samples undergo washing before confirmation. The comprehensive lab procedure from Accessioning to Confirmation is assessed based on both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 compliance.
