Hair analysis emerges as a robust means for identifying drug and alcohol consumption. It offers an extensive timeline of substance use by embedding biomarkers in the strands of growing hair. When the sample is obtained near the scalp, it can extend the detection timeframe for substances to roughly 90 days. Hair is easy to gather, relatively tamper-resistant, and straightforward to transport.
A strand sampling of 1.5 inches comprising about 200 hair strands (equivalent to the dimensions of a #2 pencil) nearest the scalp yields 100mg, deemed optimal for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the sample is advised. A jeweler’s scale is recommended for precise weighing. In scenarios lacking scalp hair, a similar quantity of body hair is acceptable. References to head hair specifically denote scalp hair, while body hair includes all other variations (such as facial and axillary).
Process Overview
The primary laboratory stages in processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning initiates the incorporation of a sample into the lab system, ensuring the sample was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any pending data entry absent from an electronic chain of custody system.
Screening serves as an initial rapid assessment for drug abuse. It offers a cost-efficient approach to flag potential drug consumption in most samples; nevertheless, a positive screening result must undergo confirmation to be court-admissible. Samples appearing presumptively positive in this stage necessitate an additional confirmation test.
If a sample shows a presumptive positive indication during Screening, additional hair from the specimen is utilized for Extraction, a process that involves isolating drugs from hair at significantly lower concentrations compared to methods like urine or saliva analysis, which underscores the complexity of hair drug screening.
Confirmation for any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples are subjected to cleansing as required prior to confirmation. Each laboratory procedure from Accessioning through to Confirmation is executed in accordance with both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
