Hair analysis has emerged as a potent means for identifying the use of substances such as drugs and alcohol. Hair captures a prolonged timeline of alcohol and drug consumption by embedding biomarkers within the hairs' developing fibers. When obtained near the surface of the scalp, hair is capable of offering up to nearly a 3-month detection window for alcohol and other substances. Hair is straightforward to collect, somewhat resistant to tampering, and convenient to transport.
A section of hair measuring 1.5 inches comprising roughly 200 hair strands (approximate to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, representing the perfect amount for analysis and verification. For EtG, add-ons, and/or examinations covering more than 10 panels, 150mg of the sample is advisable. It is recommended to measure the specimen with a jeweler’s scale. If hair from the scalp isn't available, a similar quantity of body hair can be gathered. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all alternative hair types (facial, axillary, etc.).
Process Overview
The key steps in the laboratory assessment of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into the lab’s system. This encompasses verifying the sample's sealed and appropriately dispatched status, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.
Screening entails a preliminary fast assessment for substances of misuse. Although Screening provides a cost-efficient way to exclude drug usage from the majority of cases, conclusive proof in legal contexts requires a positive screen to be verified. Any samples reading as presumptively positive during Screening mandate further verification.
Should a sample read as presumptively positive within Screening, additional hair is extracted from the initial sample and readied for Extraction. During this process, drugs are derived from hair in a significantly lower concentration than through alternative methods (such as urine or oral fluid), highlighting why hair drug screening is the most challenging method to execute.
Confirmation of any affirmative screening finding is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample undergoes washing prior to confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation undergoes evaluation under both CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 criteria.
