Hair testing has emerged as a valuable resource in identifying substance and alcohol consumption. Hair captures a long-standing record of alcohol and drug use by embedding biomarkers within the fiber of the developing hair shaft. Gathered near the scalp, hair can offer up to about a three-month detection period for alcohol and various drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.
A segment of 1.5 inches consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample size for both preliminary and confirmatory analysis. For EtG, additional elements, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. We suggest utilizing a jeweler’s scale for specimen weighing. If scalp hair isn't accessible, an equivalent portion of body hair may be taken. Reference to head hair pertains solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The drug testing result process encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary integration of a sample into a laboratory's framework. This stage ensures the sample's seal and transport are intact, designates a random LAN (Laboratory Accessioning Number), and concludes any supplementary data input not covered by an electronic chain of custody system.
Screening comprises an initial rapid assessment for substances of abuse. Although Screening is an economical approach to negate drug usage across most samples, a positive screen necessitates validation to be permissible legally. Any presumptive positive results in Screening necessitate additional confirmation.
Should a sample yield a presumptive positive from Screening, additional hair is taken from the initial batch for Extraction. In this phase, drugs are retrieved from hair at substantially lower concentrations than other methods (ex. urine or oral fluid), which heightens the complexity of hair drug screening methodology.
To verify any positive screening outcome, GC/MS, GC/MS/MS, or LC/MS/MS is employed. All samples labeled as presumptive positives undergo washing prior to confirmation where needed. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and the accreditation to ISO / IEC 17025 standards.
