Hair testing is recognized as a potent means for identifying drug and alcohol consumption. The fibers of growing hair strands trap biomarkers, providing a long-term record of alcohol and drugs. If collected near the scalp, hair can reveal drug and alcohol presence up to around 3 months back. The process of collecting hair samples is straightforward, resistant to tampering, and convenient to ship.
A sample of 1.5 inches length comprising roughly 200 hair strands (similar in size to #2 pencil) taken from the scalp supplies 100mg—an optimal amount for both screening and confirmation. For EtG or tests exceeding 10 panels, 150mg is advised. A jeweler’s scale is recommended for weighing the hair specimen. When scalp hair is absent, collecting an equal amount of body hair will suffice. "Head hair" refers solely to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug tests comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning registers a sample initially into a laboratory’s system. This step ensures proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and completes any missing data not covered by an electronic chain of custody system.
Screening conducts a preliminary assessment for drugs of abuse. While Screening effectively rules out drug usage for most samples cost-efficiently, positive results demand confirmation for court admissibility. Presumptively positive Screening samples need secondary confirmation.
If Screening suggests positivity, extra hair is drawn from the primary specimen for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations than in methodologies like urine or oral fluid, making hair drug testing a challenging process.
Positive Screening confirmations are carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed as necessary before confirmation. The entire procedure from Accessioning to Confirmation is thoroughly reviewed under CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
