Hair analysis has emerged as an effective resource for identifying drug and alcohol consumption. The hair strands capture biomarkers in the fibers during growth, providing a prolonged timeline of alcohol and drug use. When obtained near the scalp, hair can reveal drug and alcohol consumption up to a period of around three months. Hair collection is straightforward, it is relatively resistant to tampering, and convenient to transport.
An ideal sample for both screening and confirmation purposes consists of a 1.5-inch segment of approximately 200 hair strands (equivalent in size to a #2 pencil) situated closest to the scalp, yielding 100mg of hair. For EtG tests, add-ons, or panels exceeding 10, a specimen weighing 150mg is advisable. It's best to use a jeweler’s scale for measuring the specimen. If scalp hair is not available, a similar amount of body hair is acceptable. When we mention head hair, we specifically refer to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial incorporation of the sample into the laboratory’s system, which entails ensuring correct sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entries not covered by an electronic chain of custody system.
Screening provides an initial rapid evaluation for substances of abuse. Despite being a cost-efficient method for dismissing drug use in most samples, a positive Screening result must be verified to be acceptable in court. Samples with a presumptive positive result in Screening require subsequent confirmation.
If presume-positive results arise during Screening, additional hair from the initial specimen is prepared for Extraction. Drugs are extracted from hair at much lower concentrations compared to other methods (like urine or oral fluid), making hair drug screening the most complex methodology.
Confirmation of any positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed prior to confirmation if necessary. Every step from Accessioning to Confirmation is comprehensively reviewed in line with both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
