In the realm of drug and alcohol detection, hair sampling has emerged as a formidable method. The hair's structural matrix captures biomarkers of alcohol and drug consumption, offering a timeline of use. When taken near the scalp, this method can detect alcohol and drugs for around a three-month period. Collection is straightforward, manipulation is challenging, and transport is convenient.
A sample measuring 1.5 inches, comprising approximately 200 hair strands (akin to a #2 pencil's diameter) closest to the scalp amounts to 100mg, the optimal mass for analysis. For EtG or extended panels exceeding 10, a specimen weighing 150mg is advisable. It is suggested to utilize a jeweler’s scale for weighing the sample. Should scalp hair not be available, an equivalent amount of body hair can be used. References to head hair are specific to scalp hair only, whereas body hair encompasses other types, including facial and axillary.
Process Overview
The laboratory processing of hair drug testing involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial stage of integrating a sample into the lab system, ensuring proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and inputting any extra data not captured by an electronic chain of custody.
Screening conducts an expedited examination to detect drug abuse. Though cost-efficient for eliminating most samples, a positive result needs confirmation for judicial acceptance. Samples that yield presumptive positive results in Screening progress to secondary testing.
In cases of presumptive positives during Screening, additional hair is taken from the original specimen for Extraction. At this stage, drugs are isolated from hair at concentrations significantly lower than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any screening-positive involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed as necessary before confirmation. The entire lab process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards accreditation.
