Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of substance use by embedding indicators in the strands as they develop. When sampling is done near the scalp, it offers an approximately 3-month window of detection for alcohol and drugs. The collection of hair is uncomplicated, fairly resistant to tampering, and straightforward to transport.
A sample of 1.5 inches comprising about 200 hair strands (approximating the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both screening and validation. For EtG, additional tests, and/or panels exceeding 10, 150mg is suggested. Utilizing a jeweler's scale for weighing the sample is advisable. If scalp hair isn’t available, an equivalent quantity of body hair can be utilized. When "head hair" is mentioned, it specifically denotes scalp hair. "Body hair" includes all other varieties (facial, underarm, etc.).
Process Overview
The principal phases in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step in integrating a sample into a lab's system. This process checks the sample's sealing and shipping integrity, assigns a random LAN (Laboratory Accessioning Number), and handles any needed data entry not covered by an electronic chain of custody system.
Screening serves as an initial, rapid assessment for substance abuse. While Screening efficiently eliminates drug involvement for most samples, positive results require confirmation to be legally valid. Samples that test positive in Screening necessitate further verification.
In cases of presumptive positivity during Screening, extra hair is extracted from the initial sample to prepare for Extraction. This phase extracts drugs from hair at lower concentrations relative to other methods (e.g., urine or oral fluid), underscoring the complexity of conducting hair drug screenings.
Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed if needed prior to confirmation. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly called "hair follicle tests," the analysis focuses on the hair strand, not the hair follicle beneath the scalp.
