Hair analysis is recognized as an effective method for detecting the usage of drugs and alcohol. Hair captures biomarkers within the fibers of the growing strand, offering a long-term record of substance use. When collected near the scalp, hair can present up to an estimated 3-month detection span for drugs and alcohol. It's straightforward to gather, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches, comprising around 200 hair strands (approximately the thickness of a standard #2 pencil) nearest to the scalp, provides 100mg of hair—the ideal quantity for screening and confirmation. For EtG, additional tests, and/or evaluations exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be used. References to head hair strictly mean scalp hair, while body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial processing of a sample into the lab’s system. This step involves confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by a digital chain of custody system.
Screening entails a preliminary check for substances of abuse. While Screening is an economical method to exclude drug usage for most samples, a positive result requires Confirmation for legal admissibility. Any samples that are presumptively positive in Screening necessitate a secondary Confirmation.
Presumptive positives in the Screening phase lead to additional hair being extracted from the original sample for Extraction. During this process, drugs are extracted from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is considered the most challenging method to execute.
Confirmation of positive Screening outcomes utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if needed. The entire laboratory sequence from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 standards.
