Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as a robust method for uncovering drug and alcohol consumption. Hair captures a historical record of alcohol and drugs by encasing biomarkers within the fibers of the growing hair strand. A sample taken close to the scalp can offer nearly a three-month timeframe for detecting alcohol and other drugs. Hair collection is straightforward, relatively challenging to tamper with, and simple to transport.
A 1.5-inch section of approximately 200 hair strands (about the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the preferred sample size for both screening and confirmation processes. For EtG, add-ons, and/or tests exceeding 10 panels, it is advisable to have 150mg of the sample. Using a jeweler's scale to weigh the sample is recommended. If scalp hair isn't available, a comparable amount of body hair may be gathered. Head hair specifically refers to scalp hair, while body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The key stages in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial sample processing into a lab's system. This process entails verifying proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any further data entry absent in an electronic chain of custody system.
Screening performs an initial rapid assessment for potential substance abuse. Although Screening offers a cost-efficient method to exclude drug use for most samples, positive screens must undergo confirmation for legal admissibility. Any samples that show presumptive positivity during Screening require additional confirmation.
When a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. This step involves extracting drugs from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), accentuating the complexity of hair drug screening methodology.
Verification of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of all presumptive positive samples occurs prior to confirmation. The full lab process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation as well as the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", the actual analysis examines the hair strand, not the follicle beneath the scalp.
