Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of drug and alcohol use by trapping biomarkers within the strands of growing hair. Collected at the scalp, hair can offer up to a roughly 3-month detection period for substances like alcohol and other drugs. Hair collection is straightforward, resistant to tampering, and conveniently portable.
A 1.5-inch segment consisting of around 200 hairs (approximating the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair—ideal for initial testing and subsequent verification. For tests involving EtG, additional parameters, and/or over 10 panels, a 150mg sample is suggested. We advise weighing the sample on a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair might be used. When discussing head hair, we mean scalp hair only. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test outcome consists of four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the start of a sample’s entry into a lab's system. This step ensures that the sample was properly sealed and transported, assigns a new LAN (Laboratory Accessioning Number), and completes any missing data not covered by an electronic chain of custody system.
Screening is a preliminary check for substances of abuse. While it's a cost-effective way to clear a significant number of samples of drug use, positive screenings require validation to be legally defensible. Samples with a suspected positive outcome during Screening need a secondary verification.
If a sample shows a presumptive positive in Screening, additional hair is taken from the original sample and prepared for Extraction. During Extraction, drugs are removed from hair at a significantly lower concentration compared to other methods (like urine or saliva), which explains why hair drug testing is notably challenging to perform.
Verification of any positive Screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleansed as needed prior to Confirmation. The complete process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 certification.
