Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair can chronicle an extended history of these substances by encapsulating biomarkers within the hair strand's growing fibers. When clipped near the scalp, hair can reveal up to roughly a 3-month timeframe for alcohol and other substances. Hair is easy to gather, somewhat resistant to tampering, and straightforward to transport.
A 1.5-inch section of about 200 hairs (roughly the thickness of a #2 pencil) nearest the scalp ensures a 100mg hair sample, the optimal amount for testing and validation. For EtG, supplemental tests, or evaluations exceeding 10 panels, a 150mg specimen is advised. We suggest using a jeweler's scale to determine the specimen's weight. If scalp hair is absent, a comparable quantity of body hair may be used. 'Head hair' refers exclusively to scalp hair, while 'body hair' encompasses all other varieties (e.g., facial, axillary).
Process Overview
The key stages in the lab-handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial treatment of a sample as it enters a lab's workflow. This step ensures the sample's proper sealing and transport, assigns it a random LAN (Laboratory Accessioning Number), and completes any missing data not captured by an electronic chain of custody system.
Screening entails an initial rapid check for illicit substances. Screening serves as a budget-friendly method to eliminate drug usage in most samples, but evidence in court demands a positive screen to be confirmed. Samples showing preliminary positive results during Screening need subsequent verification.
Should a sample be found presumptive positive at the Screening phase, additional hair is retrieved from the initial sample for Extraction. In this phase, drugs are extracted from hair at notably lower levels than other methods (such as urine or oral fluid), highlighting the complexity of hair drug testing.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All initially positive samples are cleansed before confirmation, if needed. The full testing process, from Accessioning to Confirmation, is assessed following both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
