Hair analysis has established itself as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by encapsulating biomarkers within the strands as they grow. When sourced near the scalp, it can provide a detection period of up to roughly 90 days for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch section comprising around 200 hairs (comparable to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for testing and verification. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't accessible, a similar volume of body hair can be gathered. By head hair, we mean scalp hair exclusively. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The primary processes in lab-based drug test analysis are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory database. This process includes verifying the sample's seal and shipment, generating a random LAN (Laboratory Accessioning Number), and filling in any additional data not captured by an electronic chain of custody.
Screening provides an initial rapid assessment for drug abuse. Although efficient for excluding drug use in most samples, a positive screen must be validated for court acceptance. Samples suspected positive in Screening require further confirmation.
If Screening suggests a positive result, additional hair is extracted from the initial sample for Extraction. This step extracts drugs from hair at a notably lower concentration than other methods (e.g., urine or saliva), making hair drug testing one of the toughest methodologies.
Confirmation of any positive screen result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleaned prior to confirmation if necessary. The end-to-end lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 criteria.
Advantages of hair drug testing:
Limitations:
Note: Although frequently termed as "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the scalp.
