Hair analysis is increasingly recognized as a reliable method for identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by capturing biomarkers within its growing strands. When extracted near the scalp, hair can reveal a detection timeframe of up to three months for alcohol and drugs. Collecting hair is straightforward, comparatively hard to tamper with, and convenient to send.
To obtain an ideal sample for analysis, a 1.5-inch segment consisting of roughly 200 hair strands (roughly equivalent to a #2 pencil's width) close to the scalp, yielding 100mg, is recommended. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. We advise measuring the sample on a jeweler's scale. If scalp hair is unavailable, an equivalent portion of body hair can be used. By head hair, we mean scalp hair solely. Body hair includes other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test samples involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample undergoes initial processing within the lab system, which involves validating its proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data entry absent from an electronic chain of custody system.
The Screening stage entails a swift preliminary evaluation for drug abuse. Although Screening offers a cost-efficient method to dismiss drug use in most samples, a positive result necessitates confirmation to be acceptable in legal contexts. Any samples presumptively positive in Screening require secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair is sourced from the initial sample and set for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug testing one of the most challenging methodologies.
Using GC/MS, GC/MS/MS, or LC/MS/MS, positive screening results undergo Confirmation. All samples with presumptive positives are cleansed before confirmation if necessary. The complete lab process from Accessioning through Confirmation is examined under the CAP (College of American Pathologists) Hair criteria alongside ISO / IEC 17025 accreditation.
