Hair analysis has been recognized as an effective means for identifying drug and alcohol consumption. This method provides an extended record of alcohol and other substances by capturing biomarkers within the growing hair's structure. When sourced close to the scalp, hair offers roughly a 3-month timeframe for detection of alcohol and drugs. It's easy to obtain, somewhat resistant to tampering, and straightforward to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (similar to a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen size of 150mg is preferred. It's advisable to measure the specimen with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair is acceptable. Note, head hair specifically denotes scalp hair only, whereas body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The critical phases in the lab analysis of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample into the lab’s database. This step ensures the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any remaining data input not managed by an electronic chain of custody system.
Screening conducts a preliminary check for substance misuse. Though Screening is a cost-efficient method to exclude drug use in most samples, a positive screen necessitates confirmation to be legally recognized. Samples testing preliminarily positive in Screening mandate additional confirmation.
Should a sample test preliminarily positive during Screening, additional hair is extracted from the original specimen for Extraction. In this phase, drugs are detached from hair at lower concentrations compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleaned before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
