Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair offers an extensive timeline of substance use by capturing biomarkers within its growing fibers. When gathered near the scalp, it delivers up to a 3-month detection range for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly the diameter of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is suggested. It is advised to utilize a jeweler’s scale for precise measurement. Should scalp hair be inaccessible, a comparable quantity of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" denotes all other hair types (e.g., facial, axillary).
Process Overview
The four primary stages in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample's entry into the lab's system. This step ensures the sample’s proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and finalizes any additional data not included by an electronic custody chain.
Screening conducts an initial, rapid assessment for drug abuse. Although Screening is cost-efficient for excluding drug use in most cases, any positive indications must be verified to be legally valid. Any sample that tests positive in Screening requires secondary confirmation.
Should a sample test positive during Screening, additional hair is extracted from the main sample and prepped for Extraction. During Extraction, drugs are removed from hair at much lower levels than in other methods (like urine or saliva), making hair analysis notably complex to execute.
Confirmation of positive results is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples presumed positive are cleaned before confirmation if necessary. The whole lab procedure from Accessioning to Confirmation is evaluated under both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation standards.
