Hair examinations have gained recognition as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug exposure by enclosing biomarkers within the fibers of the growing hair shaft. Collected near the scalp, hair can present a detection window of up to approximately three months for alcohol and other drugs. Hair sampling is uncomplicated, relatively resilient to tampering, and straightforward to transport.
A 1.5-inch section comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal sample for screening and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is inaccessible, a similar quantity of body hair can be used. References to head hair imply scalp hair solely. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key steps in the laboratory analysis for drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary introduction of a sample into a laboratory’s framework. This step verifies that the sample was securely sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and addresses any supplementary data entry not captured by an electronic chain of custody system.
Screening serves as an initial baseline evaluation for drug abuse. Although Screening is cost-efficient for dismissing drug use in most samples, a positive screen necessitates confirmation to be valid in legal settings. Presumptive positive samples in Screening require a secondary affirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug analysis one of the most challenging methodologies to execute.
The Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing prior to confirmation as necessary. The comprehensive laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Frequently termed as "hair follicle tests", the test itself examines the hair strand rather than the follicle beneath the scalp.
