Hair testing is recognized as a strong method for identifying drug and alcohol consumption. Hair holds a detailed history of alcohol and drugs by capturing biomarkers within the strands as they grow. When harvested near the scalp, hair offers up to around a 3-month window for detecting alcohol and drugs. Hair is simple to gather, tough to tamper with, and straightforward to transport.
A 1.5-inch portion of roughly 200 hair strands (similar to a #2 pencil in size) positioned closest to the scalp yields 100mg of hair, the ideal quantity for testing and confirmation. For EtG, supplementary tests, and/or analyses exceeding 10 panels, a 150mg sample is suggested. It is advisable to weigh the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent volume of body hair may be used. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The four central stages in the laboratory process for determining a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This entails validating that the sample was adequately sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.
Screening entails a rapid primary check for drugs of abuse. While Screening is a cost-efficient method to dismiss drug use in most samples, a positive screen requires confirmation for judicial acceptance. Any samples that show presumptive positivity in Screening mandate a further confirmation.
Should a sample emerge presumptively positive during the Screening phase, more hair is retrieved from the original sample and readied for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), which accounts for the complexity of hair drug screening.
Confirmation of a positive screen result is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The entirety of the lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
