Hair testing is now recognized as a potent method for uncovering drug and alcohol use. It captures a detailed historical record of substance intake by embedding biomarkers within the hair's growing structure. When taken close to the scalp, hair offers a detection span for alcohol and other drugs reaching up to roughly 3 months. Hair collection is straightforward, difficult to tamper with, and convenient to transport.
By acquiring a 1.5-inch hair section of about 200 strands (comparable to a #2 pencil) nearest to the scalp, you obtain 100mg of hair—the perfect sample size for screening and verification. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is advised. Using a jeweler's scale to measure the specimen is recommended. If scalp hair isn't an option, a comparable volume of body hair can be used. References to head hair specifically mean scalp hair. Body hair pertains to any other hair types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the initial integration of a sample into the lab system. This phase ensures the sample was securely sealed and duly shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry that isn't covered by an electronic chain of custody system.
Screening serves as a preliminary inspection for substance abuse. Though a cost-efficient means to clear most samples of drug usage, a positive result in Screening requires confirmation for legal acceptance. Presumptive positive samples in Screening mandate further confirmation.
In cases of presumptive positive results at the Screening phase, additional hair is sourced from the initial specimen for Extraction. Here, drugs are extracted from hair at notably lower concentrations than found in other methods (such as urine or oral fluid), underscoring the complexity of hair drug screening methodologies.
Confirmation for any positive result revealed in Screening happens via GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample undergoes a washing procedure before confirmation if necessary. The entirety of the laboratory course from Accessioning to Confirmation is reviewed following both the CAP (College of American Pathologists) Hair specifications and accreditation under ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly called "hair follicle tests", the test examines the hair strand itself and not the follicle beneath the scalp
