Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair can capture a long-term history of substance use by embedding biomarkers within the strands of hair as they grow. When hair is collected near the scalp, it offers approximately a 3-month timeframe for detecting alcohol and other substances. Hair is easy to gather, challenging to tamper with, and simple to transport.
A 1.5-inch sample consisting of around 200 hair strands (roughly the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair is not available, an equivalent amount of body hair can be collected. When referencing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair (facial, axillary, etc.).
Process Overview
The pivotal steps in a laboratory's drug testing workflow include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory’s system. This step involves ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any required data entry not included in an electronic chain-of-custody system.
Screening provides a preliminary assessment for substances of abuse. While it’s a cost-efficient method to exclude drug use in most cases, a positive screen requires confirmation for legal admissibility. Samples that show a preliminary positive in Screening necessitate a secondary confirmation.
If a sample shows a preliminary positive in Screening, additional hair is taken from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or saliva), marking hair drug testing as the most challenging technique to conduct.
Confirmation of any preliminary positive screen is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all samples with a preliminary positive result are cleansed as necessary. The complete laboratory sequence from Accessioning to Confirmation is scrutinized against both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly termed as "hair follicle tests", the test examines the hair strand and not the follicle beneath the scalp.
