Increased usage of hair follicle drug tests has become prevalent in recent years. Many employers, legal entities, and addiction specialists now prefer hair tests over traditional urine exams. These tests are favored by zero-tolerance employers, judicial systems, and probationers due to their extensive 90-day detection period, direct observation during collection, and strong resistance to tampering. However, urine tests remain superior for detecting recent use within five days.

Hair testing has emerged as an influential method for detecting drug and alcohol consumption. Hair strands offer an extended historical record of alcohol and drug usage by capturing biomarkers within the strands' fibers as they grow. When hair is cut close to the scalp, it can offer an approximate 3-month timeframe for detecting alcohol and drug use. Hair collection is straightforward, moderately challenging to tamper with, and easy to transport.
A 1.5-inch section with around 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, or assessments exceeding 10 panels, a 150mg sample is advised. It is recommended to weigh this specimen using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be gathered. Head hair explicitly refers to scalp hair, whereas body hair encompasses other types like facial and axillary hair.
Process Overview
The four fundamental procedures in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the first step of integrating a sample into a laboratory system. This process includes checking that the sample is sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry not supplied by an electronic chain of custody system.
Screening performs an initial rapid review for substances of abuse. Screening is cost-efficient for excluding drug usage in the majority of samples, but a positive result requires confirmation to be legally valid. Samples that show a presumptive positive in the Screening stage necessitate a subsequent confirmation.
If the Screening process yields a presumptive positive, additional hair is extracted from the original specimen for the Extraction stage. Here, drugs are isolated from hair at significantly lower concentrations compared to alternative methodologies (e.g., urine or saliva), making hair drug testing the most intricate methodology.
A positive screening outcome is confirmed with GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleansed before undergoing confirmation as necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair category and the accreditation aligned with ISO / IEC 17025 standards.
