Hair testing is now recognized as a robust instrument for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drug intake by embedding biomarkers within the strands of developing hair. When sampled near the scalp, hair offers a detection timeframe of up to three months for alcohol and drugs. Gathering hair samples is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch sample consisting of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for both screening and confirming tests. For EtG, additions, or tests exceeding 10 panels, 150mg of hair is advised. We advocate for using a jeweler’s scale for measuring the specimen. If scalp hair is not available, an equal quantity of body hair may be used. While discussing head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing step whereby a sample is introduced into a laboratory's system. This step includes confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not supplied by an electronic chain of custody system.
Screening entails an initial rapid test for detecting drugs of abuse. Although Screening serves as a cost-efficient method for negating drug use in most samples, a positive result requires confirmation for court acceptance. All samples with presumptive positivity during Screening necessitate subsequent confirmation.
Should a sample show presumptive positivity in the Screening phase, additional hair is extracted from the initial sample for the Extraction process. In this step, drugs are withdrawn from hair at much lower concentrations than through other methods (e.g., urine or oral fluid), explaining why hair drug testing is notably complex to administer.
Confirmation involves verifying any positive screening outcome using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing presumptive positivity are cleansed before confirmation if needed. The entire process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and is ISO / IEC 17025 accredited.
Advantages of hair drug testing:
Limitations:
