Considered now as a significant instrument, hair testing effectively detects drug and alcohol consumption. The hair shaft's proteins capture biomarkers, offering a long-term overview of alcohol and drug exposure. Positioned near the scalp, hair provides an approximate 3-month detection timeframe for substances like alcohol and drugs. This method is easy to gather, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch portion of about 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, ideal for both screening and confirmation processes. For EtG, additional requirements, and/or tests exceeding 10 panels, 150mg of hair is advised. Using a jeweler's scale for weighing the specimen is recommended. If scalp hair is not available, an equivalent quantity of body hair can be collected. Head hair pertains exclusively to scalp hair. Conversely, body hair encompasses all other types of hair (including facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial phase of processing a sample into the laboratory's database. This stage involves ensuring the sample's proper sealing and transport, generating a random LAN (Laboratory Accessioning Number), and executing any ancillary data entry absent in an electronic chain of custody system.
Screening conducts an initial rapid assessment for substance abuse. Despite being a cost-efficient means to identify drug usage for most samples, any positive screens necessitate confirmation to be deemed court-admissible. Samples designated as presumptively positive during Screening require subsequent validation.
For samples presented as presumptively positive in Screening, additional hair is extracted from the initial specimen for the Extraction phase. Here, drugs are isolated from hair at relatively low concentrations compared to other methods (e.g., urine or oral fluid), contributing to the added difficulty of hair drug screening.
Confirming any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Required presumptive positive samples undergo washing before the confirmation process. The comprehensive laboratory procedure, spanning from Accessioning to Confirmation, aligns with the CAP (College of American Pathologists) Hair designation, as well as the accreditation in compliance with ISO / IEC 17025 standards.
