Hair analysis is widely recognized as an effective means for identifying drug and alcohol consumption. Hair records a prolonged history of alcohol and drug use by encapsulating biomarkers within the hair strand's fibers as it grows. A sample taken near the scalp can offer a detection window of nearly 3 months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (roughly the thickness of a #2 pencil) close to the scalp will yield 100mg, the perfect quantity for both testing and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a specimen weighing 150mg is advised. It is beneficial to use a jeweler's scale for accuracy. If scalp hair isn't available, a comparable amount of body hair can be collected. When discussing head hair, we mean scalp hair exclusively; body hair encompasses other hair varieties (e.g., facial, axillary, etc.).
Process Overview
The core stages in processing drug test results in a lab are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the lab's system. This involves checking the sample's seal and proper shipping, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic documentation system.
Screening acts as a preliminary assessment for drug abuse. Although cost-effective for excluding drug use in most samples, a positive result in Screening requires Confirmation to be legally valid. A secondary confirmation is mandatory for samples that show a presumptive positive in Screening.
Should a sample show a presumptive positive during Screening, more hair is extracted from the original sample for the Extraction phase. In this phase, drugs are isolated from hair at significantly lower amounts compared to other methods (like urine or oral fluid), making hair drug analysis notably challenging to execute.
Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples showing presumptive positives undergo washing before confirmation if needed. The full laboratory process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 standards.
