Hair analysis is increasingly recognized as an effective means for detecting alcohol and drug consumption. By capturing biomarkers within the strands of growing hair, it provides an extended history of substance use. When samples are collected near the scalp, they can potentially offer a detection window for substances spanning up to three months. The collection process for hair is straightforward, with minimal adulteration risk and convenient for shipping.
Collecting a 1.5-inch segment consisting of roughly 200 hairs (comparable to the diameter of a #2 pencil) from near the scalp yields about 100mg, ideal for both primary screening and confirmatory tests. For tests including EtG, add-ons, and those with over 10 panels, a recommendation of collecting 150mg is made. Using a jeweler’s scale for weighing is advised. If scalp hair is not obtainable, an equivalent amount of body hair may be used. References to head hair specifically mean scalp hair, while body hair encompasses all other types (such as facial and axillary).
Process Overview
The laboratory processing of drug test samples follows four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the lab's system by ensuring the sample's integrity in terms of proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any data entry tasks not automated by an electronic chain of custody.
Screening serves as a preliminary inspection for drug presence. Although this is a cost-efficient method to exclude drug use for most samples, any positive screens must be confirmed for legal admissibility. Samples showing preliminary positive results in Screening necessitate further confirmation.
When a sample shows presumptive positivity at the Screening phase, additional hair is extracted from the original sample for the Extraction process. Here, drug compounds are separated from the hair matrix at significantly lower concentrations compared to other matrices like urine or saliva, highlighting the complexity of hair drug testing.
In the Confirmation stage, any initially positive screenings are re-evaluated using GC/MS, GC/MS/MS or LC/MS/MS techniques. Prior to confirmation, these samples undergo washing as necessary. All processes from Accessioning through Confirmation adhere to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
