Regarded as a robust means for uncovering alcohol and drug use, hair testing offers a comprehensive retrospective by encapsulating biomarkers within the hair's fiber strands during growth. Sampling hair near the scalp enables detecting substances for roughly three months. The collection process is straightforward, it’s challenging to tamper with hair, plus it ships effortlessly.
Securing a 1.5-inch portion of around 200 hair strands (similar to a #2 pencil's thickness) nearest to the scalp yields 100mg, ideal for both screening and confirmation. For EtG or tests surpassing ten panels, 150mg is suggested. We advise employing a jeweler’s scale for weighing. Should scalp hair not be an option, equivalent body hair could substitute. For head hair, we mean exclusively scalp hair. Body hair encompasses all other varieties (axillary, facial, etc.).
Process Overview
The key stages in lab analysis for drug testing encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning handles the sample’s entry into the lab's network. It ensures the sample's seal and shipping are intact, assigns a random LAN (Laboratory Accessioning Number), and supplements any missing information not present in the digital custody chain.
Screening delivers a rapid primary evaluation for substance abuse. Although Screening efficiently negates drug use in most samples at a low cost, a confirmed screen is necessary for judicial validity. Any Screening samples showing presumptive positivity demand further confirmation.
Should the Screening phase indicate a presumptively positive outcome, additional hair is retrieved from the initial sample and processed for Extraction. Here, drug compounds are drawn from the hair in much more diluted concentrations than through alternate techniques (e.g., oral fluid or urine), rendering hair drug analysis particularly demanding.
The GC/MS, GC/MS/MS, or LC/MS/MS techniques perform the Confirmation on any positively screened results. All presumptive positives undergo a cleaning protocol before confirmation if deemed necessary. The whole lab operation covering Accessioning through Confirmation adheres to both CAP (College of American Pathologists) standards and ISO/IEC 17025 accreditation.
