Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. The hair, by embedding biomarkers within its fibers as it grows, offers an extended historical account of substance use. When sampled near the scalp, it can reveal up to a 90-day detection period for alcohol and drugs. Collecting hair is straightforward, resistant to tampering, and convenient for transport.
An ideal test sample comprises a 1.5-inch section of roughly 200 hair strands (similar in size to a #2 pencil) near the scalp, yielding 100mg of hair for optimal analysis. For tests involving EtG, additional markers, and/or more than 10 panels, a 150mg specimen is advised. It's best to weigh the sample using a jeweler's scale. If head hair is unavailable, a comparable quantity of body hair may be used. ‘Head hair’ specifically denotes scalp hair, whereas ‘body hair’ encompasses all other types (facial, underarm, etc.).
Process Overview
The laboratory drug test processing cycle includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the introductory stage that incorporates a sample into the lab's processing system. Key tasks involve confirming the sample's secure sealing and shipping, generating a random Laboratory Accessioning Number (LAN), and entering any data omitted from an electronic custody chain.
Screening acts as an initial assessment for substances of abuse. Though cost-efficient and effective at ruling out drug presence in most samples, screenings yielding positive results must undergo confirmation for validity in legal settings. Subsequent verification is required for any samples deemed positive in Screening.
Presumptive positives during Screening lead to additional hair being taken from the initial sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), contributing to the challenge of hair drug testing.
Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Pre-confirmation treatments with washing are applied as necessary. The entire lab process—from Accessioning to Confirmation—is scrutinized under the CAP Hair guidelines and ISO/IEC 17025 accreditation standards.
