Hair testing is now regarded as a potent method for identifying drug and alcohol consumption. Hair captures a long-term timeline of alcohol and drug use by embedding biomarkers in the strands of hair in growth. When gathered closely to the scalp, hair can offer up to a 3-month detection span for alcohol and drugs. Hair is easy to gather, moderately hard to tamper with, and convenient to transport.
A sample length of 1.5 inches containing about 200 strands (around the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, ideal for screening and validation. For EtG, extras, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. We advise using a jeweler's scale for weighing. If scalp hair isn't available, a proportionate amount of body hair may be utilized. Head hair denotes scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a lab's system. It entails ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any missing data not present via an electronic chain of custody.
Screening encompasses a preliminary rapid assessment for substance abuse. While Screening is a cost-efficient method to exclude drug use in most cases, a positive screen requires validation to be legally admissible. Presumptive positives in Screening need a secondary verification.
For samples with presumptive positives in the Screening phase, additional hair is extracted from the original sample for Extraction. In this phase, drugs are retrieved from hair at significantly reduced concentrations than other methods (e.g., urine or saliva), making hair drug testing the most challenging methodology.
Verification of any positive screen result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before verification as necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 certification.
Advantages of hair drug testing:
Limitations:
Note: Despite being called "hair follicle tests", the analysis examines the hair strand and not the follicle beneath the skin.
