Hair analysis is now regarded as an effective means for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drugs by embedding biomarkers within the fibers of the hair strand as it grows. Hair collected near the scalp can offer up to roughly a 3-month time frame for detecting alcohol and drugs. It's straightforward to gather, relatively hard to tamper with, and convenient for shipping.
A sample of 1.5-inch hair, consisting of approximately 200 strands (the width akin to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmation. For tests including EtG, additional components, or beyond 10 panels, 150mg of hair is advisable. It's advisable to weigh the hair using a jeweler's scale. In the absence of scalp hair, a comparable amount of body hair may be used. When discussing head hair, we specify scalp hair alone. Body hair encompasses all other forms like facial and axillary hair.
Process Overview
There are four primary stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a lab’s system. This process includes checking that the sample is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data not captured by an electronic chain of custody system.
Screening entails an initial rapid evaluation for drugs of abuse. Though Screening economically clears most samples from drug usage suspicion, a positive outcome necessitates confirmation for legal admissibility. Samples showing presumptive positives in Screening mandate further Confirmation.
In the event a sample yields a presumptive positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. At this stage, drugs are drawn from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), rendering hair drug screening the most challenging method to execute.
Positive screenings undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives get washed beforehand if required. From Accessioning to Confirmation, the entire lab process undergoes review under CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", this test processes the hair strand and not the follicle beneath the scalp.
