Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair captures a historical record of alcohol and drug intake by embedding biomarkers in the hair strand as it grows. When taken near the scalp, hair samples can offer a detection period of up to three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A segment of 1.5 inches, comprising around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmation tests. For EtG, additional tests, or comprehensive tests over 10 panels, a 150mg sample is advised. It is recommended to measure the sample on a jeweler's scale. If scalp hair is inaccessible, an equivalent volume of body hair may be sourced. When mentioning head hair, scalp hair is implied. Body hair encompasses other types like facial or axillary hair.
Process Overview
The lab processing of drug tests encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial handling of a sample in a lab’s system. This process ensures the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data not covered by an electronic chain of custody system.
Screening offers a preliminary quick assessment for drugs of abuse. While Screening serves as a cost-efficient approach to dismiss drug usage in most samples, a positive result mandates confirmation for legal purposes. Samples that are presumptively positive need further validation.
If a sample shows a presumptive positive during Screening, additional hair is extracted from the original sample for further Extraction. During Extraction, drugs are retrieved from the hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening represents the most challenging methodology to undertake.
The Confirmation of any positive screening findings is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive results undergo washing before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated according to the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
