Seen as a strong method for detecting substance and alcohol consumption, hair testing covers a prolonged timeline by embedding biomarkers in the development of the hair strand. When gathered near the scalp, hair can yield a detection period of up to around three months for alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A sample of 1.5-inch consisting of approximately 200 strands (comparable to a #2 pencil's diameter) taken nearest to the scalp produces 100mg of hair, which is ideal for examination and validation. For EtG, additional tests, and/or panels exceeding ten, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale to weigh the sample is advisable. In the absence of scalp hair, an equivalent body hair amount may be secured. References to head hair specifically mean scalp hair. Body hair encapsulates all other varieties (facial, axillary, etc.).
Process Overview
Accessioning, Screening, Extraction, and Confirmation are the cardinal stages in processing a test result in a laboratory.
Accessioning is the pivotal phase where a sample is initially entered into the lab's records. It entails checking if the sample is properly sealed and despatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not included by a digital chain of custody system.
Screening involves a rapid preliminary analysis for drugs of concern. This stage is cost-efficient, eliminating drug consumption in most samples, but a positive outcome requires validation to be court-admissible. Thus, any samples that exhibit a positive result in Screening necessitate secondary verification.
Upon a presumptive positive result in Screening, additional hair is extracted from the initial collection for the Extraction phase. Here the drug substances are drawn out from the hair at substantially lower levels than other methods (e.g., urine or saliva), making hair drug testing the most challenging to execute.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Every sample with a presumptive positive result undergoes cleaning before confirmation if necessary. The complete process from Accessioning to Confirmation is scrutinized per CAP (College of American Pathologists) Hair guidelines and the approval under ISO / IEC 17025 protocols.
