Recognized as an effective mechanism for identifying substance use, hair analysis can offer a comprehensive overview of alcohol and drug consumption by incorporating biomarkers into the hair's fibrous strands. When acquired near the scalp, it can supply a roughly three-month timeline for determining alcohol and drug presence. Hair is easy to gather, moderately resistant to tampering, and straightforward to send.
Obtaining a 1.5-inch segment consisting of around 200 hair strands (comparable to a #2 pencil) near the scalp will yield 100mg of hair, which is optimal for screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, it is suggested to use 150mg of the hair sample. Utilizing a jeweler’s scale to gauge the specimen weight is recommended. Should scalp hair be inaccessible, an equivalent volume of body hair can be collected. References to head hair imply scalp hair specifically, while body hair encompasses all other types (such as facial, underarm, etc.).
Process Overview
The fundamental steps in analyzing a drug test result in a laboratory involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial integration of a sample into a laboratory’s system. This step ensures the sample is properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and covers any absent data not included by an electronic chain of custody system.
Screening presents an initial rapid assessment for substances of abuse. Although Screening is a budget-friendly approach to negate drug use in most samples, positive screens demand validation to be recognized legally. Samples with presumptive positives in Screening necessitate additional confirmation.
Should the Screening phase yield a presumptive positive, extra hair is drawn from the original sample for further preparation in Extraction. Here, drug extraction from hair occurs at a significantly lesser concentration compared to other methods (such as urine or oral fluid), rendering hair drug testing a complex procedure.
Confirmation for any positive screening outcome employ techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, samples flagged as presumptive positives are cleansed as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized according to the CAP (College of American Pathologists) Hair requirements and ISO / IEC 17025 accreditation standards.
