Hair analysis is recognized as an effective method for detecting substance use, capturing long-term data on drug and alcohol consumption by embedding biomarkers within the strands' fibers. When taken near the scalp, the hair offers a detection period of up to about 90 days for substances. This method is straightforward to gather, resistant to tampering, and convenient for transportation.
A sample measuring 1.5 inches, roughly 200 hair strands similar in diameter to a #2 pencil, yields 100mg of hair, ideal for initial testing and verification. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advisable. Using a jeweler's scale for weighing is suggested. If scalp hair isn't available, an equivalent quantity of body hair can be used. References to head hair denote scalp hair only. Conversely, body hair includes all other varieties (like facial, axillary, etc.).
Process Overview
The drug testing in labs encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves logging a sample into a lab's system, ensuring proper sealing and shipment. This phase assigns a unique LAN (Laboratory Accessioning Number) and completes any missing data from an electronic custody chain.
Screening serves as an initial assessment for drug presence. While economical for excluding drug ingestion in most samples, a positive result necessitates confirmation to be valid in legal settings. Samples that test positive in Screening undergo secondary validation.
Presumptive positives from Screening involve additional hair extraction from the original sample for the Extraction phase, where drug concentrations in hair are lower than in other methodologies (like urine or saliva), making hair screening notably challenging.
GC/MS, GC/MS/MS, or LC/MS/MS techniques authenticate any positive screening findings. Presumptive positive samples get washed before confirmation as required. The complete lab procedure from Accessioning to Confirmation adheres to both CAP Hair designation and ISO/IEC 17025 accreditation standards.
