Lately, drug testing methods increasingly involve hair follicle tests. Employers, legal entities, and substance abuse experts often prefer hair drug tests over standard urine tests. They are favored by zero-tolerance employers, legal systems, and probationers due to their longer detection, lasting up to 90 days, and almost fraud-proof nature. Nevertheless, urine tests remain unrivaled for detecting recent drug use within a 5-day window.

Hair testing has emerged as an influential method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drugs by securing biomarkers within the hair strand’s fibers as it grows. When taken near the scalp, hair can offer a detection timeline of up to around three months for alcohol and other substances. Hair collection is straightforward, relatively tough to tamper with, and transport-friendly.
A sample size of 1.5 inches consisting of approximately 200 hair strands (approximately the thickness of a #2 pencil) close to the scalp yields 100mg of hair, an optimal amount for both screening and confirmation. For EtG add-ons or tests exceeding 10 panels, 150mg of the sample is advised. It is recommended to weigh the sample with a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair may be used. Head hair refers specifically to scalp hair, while body hair covers all other types including facial and axillary hair.
Process Overview
The key steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the preliminary processing of a sample into a laboratory’s system. It involves ensuring the sample is properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any missing data not covered by an electronic chain of custody.
Screening involves a preliminary quick assessment for drugs of abuse. Though Screening is a cost-efficient method to dismiss drug usage in the majority of samples, a positive outcome must be verified for court admissibility. Samples with presumptive positives in Screening need a secondary confirmation.
If a sample shows presumptive positivity during Screening, additional hair from the initial specimen is readied for Extraction. This stage involves extracting drugs from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as necessary. The complete laboratory process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and in compliance with ISO / IEC 17025 standards.
