Most tests require 1.5 to 2 inches of hair from the scalp or body. These tests can detect drugs, alcohol, ETG, or be customized for individual requirements.
Recently, hair follicle tests have become a preferred drug testing method. Employers, legal entities, and substance abuse experts often choose this over urine tests. Zero-tolerance policies and legal monitoring favor hair tests, offering detection over 90 days. Though for recent drug usage, within 5 days, urine tests still offer the most precise results.

Hair analysis has emerged as an effective instrument for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers within the strands of developing hair. When sourced from near the scalp, hair offers a detection range of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and conveniently transportable.
A 1.5-inch portion of roughly 200 hairs (comparable to the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for screening and verification. For EtG, supplemental tests, and/or panels exceeding 10, a specimen weight of 150mg is advisable. We suggest measuring the specimen using a jeweler’s scale. If scalp hair isn’t accessible, an equivalent amount of body hair may be obtained. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initiation of sample processing within a lab’s system. This step ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entries absent from an electronic chain of custody system.
Screening constitutes an initial rapid assessment for abused substances. Although Screening is an economical method to eliminate drug use in most samples, a positive screen requires confirmation to be valid in legal proceedings. Samples indicated as presumptively positive in Screening necessitate a subsequent confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for preparation in the Extraction phase. Here, drugs are separated from the hair at concentrations lower than those in other techniques (such as urine or oral fluid), rendering hair drug screening as one of the most challenging techniques to execute.
The Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
