Hair analysis has emerged as a robust means for identifying alcohol and drug consumption. The hair captures a comprehensive historical record of substance use by encapsulating biomarkers within the strands as they grow. When obtained near the scalp, a hair sample can reflect up to a three-month usage history for alcohol and other substances. Collecting hair is straightforward, not easily tampered with, and convenient to send.
A section of hair measuring 1.5 inches, approximately 200 strands (comparable to a #2 pencil), closest to the scalp ensures 100mg of the sample, optimal for initial and confirmatory testing. For tests including EtG, add-ons, or more than 10 panels, it is suggested to gather 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is advisable. If scalp hair cannot be procured, a proportionate quantity of body hair is acceptable. Reference to head hair pertains solely to scalp hair. Body hair encompasses all other hair varieties (such as facial, axillary, etc.).
Process Overview
The primary stages in drug test analysis at the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the preliminary input of a sample into the lab’s system, including ensuring the sample's secure seal and transport, the random assignment of a LAN (Laboratory Accessioning Number), along with supplementary data entry if not covered by an electronic chain of custody system.
Screening serves as an initial inspection for drug presence. It is an economical method for negating drug use in most samples; nonetheless, a positive screen requires validation for legal credibility. Samples flagged as presumptively positive necessitate secondary confirmation.
Upon a presumptive positive in Screening, additional hair is extracted from the primary sample and subjected to the Extraction phase. Here, drugs are eluted from hair at lower concentrations compared to other methods (e.g., urine or oral fluids). Hence, hair drug testing represents a challenging methodology.
Confirmation of any Screening positive is through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumed positives are cleansed as requisite. The complete lab process, from Accessioning to Confirmation, undergoes scrutiny under both CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 standards accreditation.
