Hair examinations are increasingly viewed as an effective method for detecting substance and alcohol consumption. Hair offers an extended timeline of substance use by trapping biomarkers within the fibers of the growing hair shaft. When gathered close to the scalp, it can deliver a detection span of up to roughly 90 days for alcohol and various drugs. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.
A 1.5-inch segment containing about 200 strands (comparable to the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample size for screening and confirmation purposes. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. The specimen should ideally be weighed on a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be obtained. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample within a laboratory's system. This process includes ensuring the sample was properly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and carrying out any supplementary data entry not covered by an electronic chain of custody system.
Screening constitutes an initial rapid evaluation for substances of abuse. While Screening offers a cost-efficient approach to eliminate drug usage for most samples, a positive outcome requires confirmation to be valid in legal proceedings. Any samples that test presumptively positive during Screening require further confirmation.
If a sample tests presumptively positive at the Screening stage, additional hair is extracted from the original specimen for the Extraction process. In this phase, substances are extracted from hair at concentrations significantly lower than those found in other methodologies (such as urine or oral fluid), making hair drug testing the most challenging methodology to execute.
Confirmation of any positive screening finding is executed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples undergo a washing process prior to confirmation, if necessary. The complete laboratory procedure from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.
