Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. This method provides an extended timeline of substance usage by embedding biomarkers within the hair strands as they grow. When obtained near the scalp, hair can offer a detection timeframe of up to three months for substances like alcohol and other drugs. The collection process for hair is straightforward, it's relatively resistant to tampering, and it can be conveniently sent for testing.
A 1.5-inch section with roughly 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the perfect sample size for testing and corroboration. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. We suggest using a jeweler's scale for accurate specimen weight measurement. If scalp hair isn't accessible, a comparable quantity of body hair can be gathered. "Head hair" relates specifically to scalp hair. Conversely, "body hair" encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is entered into the laboratory system. This step ensures the sample was sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and completes any data entry that is not automated by an electronic chain of custody system.
Screening provides a preliminary assessment for substance abuse. While it is cost-efficient for ruling out drug use in most specimens, a positive screening result requires confirmation to be valid in legal settings. Every presumptive positive from screening necessitates further confirmation.
If a specimen is considered presumptively positive during Screening, additional hair from the sample is utilized for Extraction. This phase involves isolating drugs from the hair at much lower concentrations compared to other tests (like urine or oral fluid), making hair drug testing the most challenging technique to execute.
Confirmation of positive screenings is carried out using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleansed before confirmation as needed. The entire testing procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 accreditation.
