Hair testing serves as a robust method for detecting drug and alcohol consumption. Hair can capture biomarkers in its fibers, providing a comprehensive history of substance use as it grows. When extracted near the scalp, hair can offer a detection timeline of up to three months for alcohol and drugs. Hair collection is easy, relatively tamper-resistant, and straightforward to transport.
A sample measuring 1.5 inches with around 200 hair strands (approximately the thickness of a #2 pencil) cut near the scalp yields 100mg of hair, which is optimal for both screening and confirmatory tests. For EtG, add-ons, and tests exceeding 10 panels, a specimen weighing 150mg is advisable. The specimen should ideally be weighed on a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be collected. When referencing head hair, it denotes scalp hair only. Body hair encompasses all other types, including facial and axillary hair.
Process Overview
The primary phases in the laboratory processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into a lab's system, which involves verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and executing any supplementary data entry absent in an electronic chain of custody framework.
Screening entails a preliminary rapid assessment for abuse substances. Though Screening is a cost-efficient method to exclude drug usage in most samples, any positive finding requires confirmation to be legally valid. Samples presumed positive during Screening must undergo additional confirmation.
If a sample appears presumptively positive in the Screening phase, additional hair is taken from the initial sample for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to conduct.
Confirmation of screening results occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation when necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
