Hair analysis is now viewed as a potent method for identifying drug and alcohol consumption. Hair offers a comprehensive record of alcohol and drug usage through the preservation of biomarkers within the hair strand fibers as they develop. Collected near the scalp, hair samples can provide an approximate detection timeframe of up to three months for drugs and alcohol. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.
A specimen of 1.5 inches comprising around 200 hair strands (roughly equivalent to a #2 pencil thickness) from the scalp area yields 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, and/or panels exceeding 10, a specimen weight of 150mg is advised. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an equivalent body hair sample is acceptable. Head hair is specific to scalp hair, whereas body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The lab process for determining a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into a lab’s system. This step ensures the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any outstanding data entry not provided by an electronic chain of custody.
Screening is a preliminary check for substances of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive screen must be confirmed for court admissibility. Samples testing positive in Screening require additional confirmation.
A Screening presumptive positive prompts further extraction of hair from the initial specimen. During Extraction, drugs are isolated from hair at far lower concentrations than from urine or oral fluid, making hair drug screening one of the most challenging methods to execute.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation, as appropriate. Every phase, from Accessioning to Confirmation, is audited under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
