Hair testing is widely acknowledged as a potent means for identifying drug and alcohol consumption. Hair offers an extensive timeline by capturing biomarkers within the fibers as hair grows. When taken near the scalp, it can deliver up to a 3-month window of detection for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, the perfect sample for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent amount of body hair can be obtained. Head hair specifically refers to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
Key stages in the laboratory processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample within a lab’s system. This step ensures the sample was properly sealed and shipped, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entry not offered by an electronic chain of custody system.
Screening entails a preliminary brief check for drugs of abuse. Although Screening effectively rules out drug usage in most samples, a positive screen must be verified for legal admissibility. Samples with a presumptive positive in Screening necessitate secondary confirmation.
If a sample shows a presumptive positive during the Screening phase, additional hair is taken from the original sample and prepped for Extraction. Here, drugs are extracted from the hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug testing an intricate methodology.
Confirmation of any positive screening finding is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with a presumptive positive outcome are cleaned prior to confirmation if necessary. The entire lab process, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair category and the accreditation to ISO / IEC 17025 standards.
