Hair testing is recognized as a potent method for detecting drug and alcohol consumption. Hair offers an extended chronological record of substance use by preserving biomarkers within the fibers of the growing hair strand. When cut close to the scalp, hair can signal substance use within an approximately 3-month detection period. It is effortless to collect, challenging to tamper with, and simple to transport.
Collecting a 1.5-inch sample of around 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample size for screening and validation. For tests such as EtG, add-ons, and those exceeding 10 panels, a specimen of 150mg is suggested. Utilizing a jeweler’s scale is advised for weighing the specimen. If scalp hair isn't an option, a comparable amount of body hair is applicable. When mentioning head hair, it pertains solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The principal steps in the lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is processed into the lab's system. It involves checking that the sample was properly sealed and shipped, designating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry absent from an electronic chain of custody system.
Screening constitutes an initial swift assessment for drugs of abuse. While Screening is a cost-efficient technique to negate drug use in most samples, any positive result requires confirmation to be court-admissible. Samples that indicate presumptive positivity in Screening necessitate secondary confirmation.
If Screening results in a presumptive positive, further hair is drawn from the original sample and readied for Extraction. This phase involves removing drugs from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if required. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 accreditation standards.
