Recent trends in drug testing have favored hair follicle methods. Many employers, judicial systems, and Substance Abuse professionals now prefer hair drug tests to traditional urine samples. These tests support zero-tolerance policies in workplaces, courts, and probationary contexts. Hair follicle drug tests offer a key advantage: a longer detection window, usually up to 90 days, ensuring the samples remain secure and virtually tamper-proof. Nevertheless, for detecting very recent drug use within 5 days, urine tests remain the preferred standard.

Hair analysis is now recognized as a significant means for identifying substance intake. Hair offers a retrospective timeline by embedding chemical markers within its structure as it grows. Collected near the scalp, it can reveal approximately a three-month trace of alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.
A typical 1.5-inch hair sample, comprising about 200 strands akin to a #2 pencil, yields 100mg of hair, which is considered optimal for evaluations and confirmation. For EtG testing, add-ons, and/or screens exceeding 10 panels, a 150mg sample is preferred. It's advised to measure the specimen using a jeweler’s scale. In cases where head hair is lacking, a like quantity of body hair may be used. Head hair denotes only scalp hair, whereas body hair includes other types (facial, underarm, etc.).
Process Overview
The essential phases in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the sample's initial entry into the lab’s system. This step ensures the sample was properly sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and completes any pending data entry not covered by an e-chain of custody.
Screening offers a preliminary scan for substance abuse. Though Screening is an economical means to dismiss drug usage in the majority of samples, a positive outcome necessitates further verification for courtroom validity. All presumptive positives from Screening must undergo further confirmation.
A presumptive positive from the Screening phase leads to more hair being extracted from the original sample for Extraction. Here, drugs are retrieved from hair in lower amounts compared to other methods (e.g., urine or oral fluids), making hair drug screening one of the trickiest methods to execute.
Confirmation of a positive screen uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every presumptive positive sample is cleansed before confirmation if required. The comprehensive lab process from Accessioning to Confirmation is overseen under CAP (College of American Pathologists) Hair qualification and accredited by ISO / IEC 17025 standards.
