Regarded as an impactful method for identifying drug and alcohol consumption, hair analysis presents a protracted timeline by capturing biomarkers within the fibers of the lengthening hair shaft. Hair, when sourced near the scalp, can exhibit a detection timeframe of up to around three months for alcohol and drugs. Collection is straightforward, tampering is relatively challenging, and it is simple to transport.
Gathering a hair sample of 1.5 inches, equating to 200 strands (resembling the size of a #2 pencil) nearest to the head, yields 100mg of hair, an optimal quantity for analysis and verification. For EtG, additional analyses, and/or examinations beyond 10 panels, 150mg is suggested. Usage of a jeweler’s scale is advised for weighing the sample. If scalp hair is inaccessible, the same volume of body hair is an alternative. References to head hair pertain solely to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The lab analysis of a drug test result comprises four prominent phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a sample into a lab’s framework. This step entails ensuring the sample’s secure sealing and shipping, the generation of an arbitrary LAN (Laboratory Accessioning Number), and finalizing any additional data input not delivered through an electronic custody chain.
Screening executes a rapid preliminary analysis for drugs of misuse. As a budget-friendly technique to negate drug consumption in the majority of specimens, a positive screen mandates verification for court acceptance. All tentatively positive samples from Screening necessitate further corroboration.
Should a specimen be tentatively positive in the Screening stage, more hair from the initial sample is extracted and prepped for Extraction. Drugs are drawn from hair at a considerably reduced concentration compared to alternate methods (i.e., urine or oral fluid), highlighting the intricate execution of hair drug screening.
Confirmation of any positive Screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing prior to necessary confirmation procedures. The entire procedure from Accessioning to Confirmation is always critically evaluated per both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
