Hair examinations are increasingly regarded as a potent means for identifying drug and alcohol consumption. Hair strands encapsulate historical data of substances by embedding biomarkers within their fibers. When acquired close to the scalp, hair offers a detection period of up to roughly ninety days for alcohol and various drugs. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil in thickness) nearest to the scalp yields around 100mg of hair, the preferred quantity for analysis and validation. For EtG, supplements, and/or tests beyond ten panels, a 150mg sample is advised. It’s advisable to measure the specimen using a jeweler's scale. If scalp hair can't be provided, an equivalent quantity of body hair may suffice. Reference to head hair pertains specifically to scalp hair. In contrast, body hair includes other types (facial, axillary, etc.).
Process Overview
The laboratory process for finalizing a drug test comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary entry of a sample into a lab’s framework. Steps in this phase include checking sample integrity during sealing and shipping, assigning it a random Labor Accessioning Number (LAN), and completing any necessary data entry omitted by digital chain of custody systems.
Screening serves as a preliminary assessment for substance abuse. Although a cost-effective method for excluding drug use in most samples, positive screenings must undergo verification to be legally valid. Samples with preliminary positive results in Screening necessitate further confirmation.
Upon yielding a presumptive positive in the Screening phase, additional hair is taken from the initial batch and readied for Extraction. This phase entails isolating drugs from hair at much lower concentrations than alternate methods (e.g., urine or saliva), amplifying the complexity of hair drug testing.
Verification of any positive screening result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo a wash before confirmation, as needed. The holistic lab procedure from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair designation along with accreditation to ISO / IEC 17025 standards.
