Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a historical record of substance usage by encasing biomarkers within the strands as they grow. Acquired close to the scalp, hair can present a detection span of up to around 90 days for substances. Collection is straightforward, tampering is challenging, and transport is hassle-free.
A 1.5-inch section consisting of roughly 200 hair strands (nearly the size of a #2 pencil) near the scalp yields 100mg, which is the optimal sample for both testing and verification. For testing involving EtG, additional panels, and/or exceeding 10 panels, a 150mg specimen is suggested. We advise verifying the specimen's weight using a jeweler's scale. If scalp hair is unavailable, a comparable amount of body hair can be obtained. The term "head hair" specifically refers to scalp hair, while "body hair" pertains to all other types (face, armpits, etc.).
Process Overview
The primary stages in the lab processing of drug test results comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample as it enters a lab’s processing system. This entails ensuring the sample was appropriately sealed and sent, assigning an anonymous LAN (Laboratory Accessioning Number), and completing any additional information entry not included by an electronic chain of custody system.
Screening provides an immediate preliminary assessment for substance use. Although Screening is a cost-efficient method to eliminate substance use on most samples, a positive outcome requires further confirmation to be legally admissible. Samples that are presumptively positive in Screening necessitate a follow-up confirmation.
If a sample yields a presumptive positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. During this phase, substances are retrieved from hair at significantly lower concentrations compared to other methodologies (like urine or saliva), highlighting why hair testing is one of the most intricate techniques to execute.
Confirmation of any positive from the Screening phase occurs using GC/MS, GC/MS/MS, or LC/MS/MS. Each sample identified as presumptive positive is cleansed before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
