Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair encapsulates a long-term profile of alcohol and drug usage by embedding biomarkers within the fibers as the hair strand grows. If collected near the scalp, hair offers an approximate 3-month timeframe for detecting alcohol and other drugs. Hair is straightforward to gather, relatively challenging to tamper with, and convenient for shipping.
A 1.5-inch segment of around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp offers 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a sample amounting to 150mg is advised. We suggest measuring the specimen with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. References to head hair specifically pertain to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).
Process Overview
The four fundamental stages in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This process includes validating the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not included by an electronic chain of custody system.
Screening performs an initial swift examination for substance abuse. Although Screening is a cost-efficient approach to exclude drug usage in most samples, a positive screen must be verified for legal admissibility. Any samples exhibiting presumptive positives in Screening require further confirmation.
If a sample yields a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen for Extraction preparation. In this stage, substances are extracted from hair at a concentration significantly lower than other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging method to execute.
Confirmation of any positive screening result is implemented through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair specifications and the ISO / IEC 17025 accreditation standards.
