Hair drug testing is now widely recognized as a potent method for detecting drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the strands as they grow. When collected near the scalp, this method offers approximately a 90-day detection period for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient to send.
A hair sample measuring 1.5 inches with around 200 strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg—ideal for both screening and confirmation. For tests such as EtG, add-ons, and those beyond 10 panels, a 150mg sample is suggested. It's advisable to weigh the hair on a jeweler's scale. If scalp hair isn't available, an equal quantity of body hair can be used. When we refer to head hair, it means scalp hair specifically. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of drug testing encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial entry of a sample into a lab's system. This step ensures the sample is sealed and shipped accurately, assigns a random Laboratory Accessioning Number (LAN), and completes any data entry absent from an electronic chain of custody system.
Screening acts as a preliminary assessment for drug abuse. Though Screening efficiently rules out drug use for most samples, a confirmed result is necessary for legal admissibility. Thus, presumptive positive findings in Screening require additional confirmation.
Should a sample register positive during Screening, extra hair from the primary sample is set aside for Extraction. Here, drugs are separated from hair at a notably lower concentration compared to methods like urine or oral fluid, highlighting the intricacy of hair drug screening.
Positive screening findings undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples deemed positive are cleansed as appropriate. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
