Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair strands chronicle a prolonged record of alcohol and other substances by capturing biomarkers within the fibers as they grow. Collected near the scalp, hair can reveal an estimated 3-month period of alcohol and drug detection. Hair sampling is easy to perform, tough to tamper with, and simple to transport.
A 1.5-inch segment encompassing roughly 200 hair strands (approximating the circumference of a #2 pencil) closest to the scalp will yield 100mg, an optimal amount for both screening and validation. For EtG, supplemental checks, and/or evaluations exceeding 10 panels, 150mg of the specimen is advisable. Utilizing a jeweler’s scale to measure the specimen is suggested. In the absence of scalp hair, a comparable amount of body hair is acceptable. "Head hair" specifically denotes scalp hair, while "body hair" describes other types like facial or axillary hair.
Process Overview
The laboratory procedure for processing a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is incorporated into a laboratory’s system. This phase encompasses ensuring the sample was adequately sealed and dispatched, allocating a unique LAN (Laboratory Accessioning Number), and finalizing any outstanding data entry not managed by an electronic chain of custody system.
Screening entails a prompt preliminary analysis for substance abuse. Even though Screening presents a cost-efficient method to dismiss drug consumption in most specimens, a confirmed positive result is required for judicial credibility. Samples testing positive during Screening mandate further verification.
Should a sample test positive in the Screening phase, additional hair is drawn from the original specimen and prepared for Extraction. Here, substances are isolated from hair in concentrations much lower than those in alternative methods like urine or oral fluids, highlighting why hair drug screening is significantly complex to execute.
GC/MS, GC/MS/MS, or LC/MS/MS are utilized for confirming any positive screening outcomes. Any presumptively positive samples undergo a washing before confirmation as dictated. The entire lab process, from Accessioning to Confirmation, is scrutinized under the guidance of CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite occasionally being called "hair follicle tests," the analysis focuses on the hair strand rather than the follicle beneath the scalp.
