Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the hair fiber as it grows. When sampled near the scalp, hair can offer a detection timeframe of up to about 3 months for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and easy to transport.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional testing, and/or over 10-panel tests, 150mg of the sample is suggested. We propose using a jeweler’s scale to weigh the specimen. If scalp hair isn’t available, an equivalent amount of body hair may be gathered. When we mention head hair, it pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four essential stages in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial setup of a sample within a laboratory’s database. This step verifies the sample’s proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug use in most samples, a positive result must be confirmed for legal admissibility. Samples that test positive in Screening require a follow-up confirmation.
If a sample registers positive in the Screening phase, additional hair is taken from the original sample and prepped for Extraction. At this stage, drugs are isolated from the hair at a much reduced concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to conduct.
Positive screening outcomes are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated in compliance with the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards accreditation.
