In recent times, hair follicle drug tests have increasingly been used for drug screening. Various employers, judicial bodies, and professionals handling substance abuse cases prefer hair tests over traditional urine tests. Employers implementing zero-tolerance policies and probationary supervisors make use of hair drug tests. The key advantage of hair testing is its extended detection range, up to 90 days, coupled with a monitored collection process, virtually eliminating the chance of tampering. However, urine tests remain effective for detecting recent drug use over the past 5 days.

Hair assessments are now considered an effective method for identifying drug and alcohol consumption. Hair captures a prolonged timeline of substance use by locking biomarkers within the strands as they grow. When taken close to the scalp, hair can reveal a detection period of up to around three months for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (similar to a #2 pencil’s thickness) nearest to the scalp will provide 100mg, the perfect amount for examination and verification. For EtG, add-ons, and/or over 10-panel tests, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn’t available, an equivalent quantity of body hair may be used. When discussing head hair, we’re specifically referring to scalp hair alone. Body hair encompasses all other hair categories (facial, underarm, etc.).
Process Overview
The primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial processing of a specimen into a lab’s system. This process includes checking if the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry missing from an electronic chain of custody system.
Screening entails a preliminary rapid check for substances of abuse. While Screening is an economical method to dismiss drug usage in most cases, a positive outcome needs confirmation to be acceptable in a legal context. Samples that are tentatively positive in Screening necessitate additional verification.
If a sample appears positive in the Screening phase, more hair is taken from the initial sample for Preparation. Here, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), emphasizing why hair drug evaluations are the most challenging method to execute.
Verification of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. All provisional positive samples are cleaned before verification as necessary. The full laboratory procedure from Accessioning to Verification is examined under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
