Hair screening is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by capturing biomarkers within the strands as they grow. When gathered near the scalp, it provides nearly a 3-month window for detecting alcohol and drugs. The collection process is straightforward, making it hard to tamper with and easy to transport.
Collecting a 1.5-inch segment from about 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg—ideal for both screening and confirming tests. For EtG and extended tests beyond 10 panels, it's recommended to use 150mg. We suggest measuring the sample on a jeweler's scale. If scalp hair is not available, a comparable amount of body hair can be used. References to head hair specifically mean scalp hair, while body hair includes other types like facial and axillary hair.
Process Overview
There are four primary phases in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, samples are initially processed into the laboratory's system, ensuring they were sealed and shipped accurately, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry missing from an electronic chain of custody system.
Screening serves as an initial rapid check for drugs. While it's a cost-efficient method to rule out drug intake for most samples, a positive screen must be confirmed to stand in court. Any samples that test positive in Screening need a secondary confirmation.
If a sample shows presumptive positivity during Screening, more hair is taken from the original sample and prepared for Extraction. Drugs at this stage are extracted at a lower concentration than in other methods like urine or oral fluid, which makes hair drug testing the most challenging method to perform.
Confirmation of a positive Screening is done via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The full lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
