Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug usage by capturing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can offer up to a three-month detection period for alcohol and other drugs. Hair collection is straightforward, somewhat challenging to tamper with, and simple to transport.
A 1.5-inch section comprising approximately 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's recommended to weigh the sample on a jeweler’s scale. If scalp hair isn't available, a corresponding amount of body hair can be collected. When referencing head hair, it indicates only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the laboratory processing of a drug test outcome comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a specimen into a laboratory's infrastructure. This step includes verifying proper sample sealing and shipment, assigning a randomized LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening is an economical method to rule out drug usage in most samples, a positive screen must be confirmed for court admissibility. Any samples preliminarily positive in Screening necessitate a secondary confirmation.
Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this stage, drugs are isolated from hair at much lower concentrations than other methodologies (e.g., urine or saliva), which is why hair drug testing is the most complex methodology to execute.
Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo necessary washing before confirmation. The entire lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.
