Hair testing is regarded as a potent means for detecting drug and alcohol consumption. This method offers a prolonged overview of substances by capturing biomarkers within the hair strands. When cut near the scalp, hair can extend an up to 90-day window of detection for both alcohol and drugs. It's straightforward to collect, hard to tamper with, and easy to transport.
A 1.5-inch portion of roughly 200 hair strands (akin to the girth of a #2 pencil) near the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG, enhancements, and/or tests exceeding 10 panels, it's advisable to gather 150mg. Using a jeweler's scale for specimen measurement is suggested. If scalp hair isn't an option, an equivalent quantity of body hair can be used. In context, head hair signifies scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key phases in laboratory drug testing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with the entry of a sample into the lab’s system. This process verifies proper sealing and shipping, assigns a LAN (Laboratory Accessioning Number), and completes any missing details not provided electronically through the chain of custody.
Screening offers a preliminary drugs of abuse check. Though a cost-efficient way for the majority, any positive screens must be confirmed for court admissibility. Samples marking positive in Screening necessitate secondary confirmation.
Should screening show a presumptive positive, additional hair from the initial sample is prepared for Extraction. Here, drugs are extracted at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening a complex process.
Confirmation for any positive screen result employs GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positives are washed before confirmation if necessary. The complete process from Accessioning through Confirmation is evaluated per the CAP (College of American Pathologists) Hair criteria and adheres to ISO / IEC 17025 standards.
