Over the past few years, hair follicle drug testing has gained traction as a preferred method for drug detection. A growing number of employers, judicial systems, and substance abuse specialists favor hair drug testing over traditional urine tests. This testing is ideal for zero-tolerance employers, court mandates, and probationary requirements. Its key advantage lies in its extended detection span, revealing drug consumption up to 90 days prior, with collection processes making deceit nearly impossible. Nevertheless, the urine test remains more dependable for detecting drug use within the recent five days.

Viewing hair testing as an effective means for identifying drug and alcohol consumption has become common. Hair offers a comprehensive history of drug and alcohol use by securing markers within the developing hair fibers. When hair is taken near the scalp, it can reveal usage for up to a 3-month period. Collecting hair is straightforward, somewhat resistant to tampering, and easy to transport.
A sample amounting to 1.5 inches from around 200 hairs (comparable to a #2 pencil's thickness) near the scalp constitutes 100mg, optimal for screening and confirmation. For tests like EtG, add-ons, and over 10-panel tests, a specimen of 150mg is advised. Using a jeweler’s scale is recommended to ensure the correct specimen weight. If there's no scalp hair available, you may gather an equivalent amount of body hair. By head hair, we imply exclusively scalp hair. Body hair encompasses all other hair types, including facial and axillary hairs.
Process Overview
The laboratory processing for a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning of a sample's processing within a lab system. This step involves confirming that the sample was properly sealed and sent, allotting a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entries not handled through an electronic chain of custody.
Screening conducts an initial rapid assessment for drugs of abuse. Although Screening efficiently rules out drug use in most samples, a positive screen must be verified for legal acceptance. Any samples showing a presumptive positive in Screening require a confirming check.
If Screening detects a presumptive positive result, additional hair is extracted from the original specimen for further Extraction. During Extraction, drugs are sourced from hair at lower concentrations than through alternatives like urine or oral fluid, highlighting hair drug testing's complexity.
To confirm a positive screening, analyses such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Prior to verification, all presumptive positive samples undergo necessary washing. The full laboratory process from Accessioning to Confirmation is evaluated in line with the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
