Hair analysis has emerged as a vital instrument for identifying drug and alcohol intake. Hair provides a prolonged timeline of substance use by embedding biomarkers within the strands of hair. When gathered near the scalp, it offers a detection window of up to about three months for drugs and alcohol. Collecting hair is straightforward, moderately resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches consisting of roughly 200 strands of hair (approximately the thickness of a #2 pencil) nearest to the scalp will yield 100mg, which is optimal for screening and verification. For EtG, additional analyses, or assessments exceeding 10 panels, a quantity of 150mg is preferred. Utilizing a jeweler’s scale to weigh the specimen is advised. If scalp hair is absent, an equivalent volume of body hair can be obtained. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
There are four primary phases in lab processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's system, which includes verifying the sample's proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry not covered by an electronic chain of custody system.
Screening entails a preliminary rapid evaluation for substances of abuse. While Screening is a cost-effective method to exclude drug use in most samples, a positive result requires confirmation to be valid in legal proceedings. Samples that are presumptively positive in Screening necessitate further verification.
If a sample turns out presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at far lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging to execute.
Confirmation of any positive screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation alongside the accreditation to ISO / IEC 17025 standards.
