Utilizing hair testing has increasingly become recognized as a significant method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the emerging hair. When obtained near the scalp, hair can deliver a detection timeline for alcohol and other drugs up to about 3 months. Hair collection is straightforward, relatively tamper-proof, and convenient for shipping.
A sample of hair measuring 1.5 inches, comprising approximately 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the optimal quantity for screening and verification. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair can be utilized. Head hair refers exclusively to scalp hair, while body hair encompasses all other kinds (facial, axillary, etc.).
Process Overview
The testing procedure in the laboratory for a drug test result includes four core phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the lab’s system. This phase involves checking that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.
Screening is a preliminary inspection for drugs of misuse. Though Screening serves as an economical approach to dismiss drug usage in most samples, any positive outcome from a screening necessitates confirmation to be recognized in legal proceedings. Samples that result in a tentative positive in Screening call for further confirmation.
In the event a sample tests tentatively positive during Screening, additional hair is gathered from the primary sample and set up for Extraction. In this phase, drugs are extracted from hair at concentrations much lower than other methods (such as urine or saliva), which makes hair drug testing the most challenging method to conduct.
Any positive result in Screening is confirmed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All provisional positive samples undergo washing prior to confirmation when necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards of accreditation.
