Hair analysis is regarded as an effective means for detecting substance and alcohol consumption. Hair records a prolonged history of alcohol and drugs by capturing biomarkers within the growing strands. When sampled near the scalp, hair can offer up to a three-month detection period for substances and alcohol. It is easy to gather, challenging to tamper with, and straightforward to transport.
A 1.5-inch portion of around 200 strands (roughly the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal amount for evaluation and validation. For EtG, additional tests, or panels exceeding 10, 150mg of hair is suggested. We advise using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, a similar amount of body hair may be used. "Head hair" refers solely to scalp hair, while "Body hair" accounts for all other types like facial and axillary.
Process Overview
The laboratory processing of a drug test outcome consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial management of a specimen within a laboratory system, ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and undertaking any further data entry absent from an electronic custody system.
Screening performs an initial rapid evaluation for substance abuse. While cost-efficient and able to eliminate drug use for most samples, a positive screening needs confirmation for legal admissibility. Any preliminary positive results in Screening warrant secondary validation.
For specimens preliminarily positive during Screening, additional hair is taken from the initial sample to prepare for Extraction. Here, drugs are extracted from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluids), hence, hair testing is the most challenging methodology.
Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all preliminary positive samples are cleansed as necessary. The complete lab process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
