Hair analysis has emerged as a significant method for identifying substance use. The long-term nature of hair allows it to capture biomarker details in the fibers of the hair as it grows. Obtaining a sample near the scalp offers a detection window of up to 90 days for substances like alcohol. The collection process for hair is straightforward, it's relatively resistant to tampering, and easy to transport.
Gathering a section of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter) from near the scalp yields 100mg—ideal for both screening and confirmation processes. For EtG testing, add-ons, or testing panels beyond 10, a sample of 150mg is advisable. It's beneficial to weigh the sample using a precise jeweler’s scale. In cases where scalp hair isn't accessible, a similar volume of body hair might be used. When mentioning head hair, it refers exclusively to scalp hair, whereas body hair includes all other types (such as facial or axillary hair).
Process Overview
The laboratory procedure for processing a drug test involves four critical stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the lab's system by confirming it was correctly sealed and shipped, while a random LAN (Laboratory Accessioning Number) is assigned and information not included in the electronic chain of custody is added.
Screening conducts an introductory assessment for drugs of abuse. This step is a cost-efficient approach for excluding drug presence in most cases; however, a positive screen necessitates further confirmation to be valid in legal contexts. Any sample indicated as positive in Screening requires further confirmation.
Should the Screening stage yield a presumptive positive, additional hair is extracted from the original sample and prepared for Extraction, where drugs are drawn from hair at significantly lower concentrations than found in other techniques (such as urine or oral fluids), making hair drug testing exceptionally challenging.
Confirmation for a positive screen result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleaned before confirmation if needed. Throughout the entire laboratory process, from Accessioning to Confirmation, oversight is maintained by CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
