Hair analysis is now recognized as an effective means for identifying substance and alcohol consumption. By embedding biomarkers within the fibers of the developing hair strand, hair can offer a long-term record of alcohol and drug intake. When collected near the scalp, hair can indicate substance use over a period of up to three months. It's easy to collect, challenging to alter, and convenient to transport.
A 1.5-inch section consisting of roughly 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is the preferred quantity for both screening and verification. For EtG, additional tests, and/or examinations over 10 panels, 150mg of hair is advised. Utilizing a jeweler’s scale for measuring the sample is recommended. In the absence of scalp hair, an equivalent amount of body hair can be collected. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The drug test process in a lab involves four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase, which involves processing a sample into a lab’s database. It entails checking if the sample was properly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any other data entry that might be absent from an electronic chain of custody system.
Screening is a preliminary rapid evaluation for substances of abuse. Although Screening is a budget-friendly method to exclude drug use in most samples, positive results require confirmation to be considered valid in legal settings. Any sample that tests presumptively positive in Screening must undergo a follow-up confirmation.
Upon a presumptive positive outcome during Screening, additional hair is extracted from the original sample for Extraction. Within this phase, drugs are extracted from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), thus making hair drug testing the most intricate method to execute.
Verification of any positive Screening results is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation as necessary. The comprehensive process from Accessioning to Confirmation is scrutinized under the guidelines of both the CAP (College of American Pathologists) Hair classification and the ISO/IEC 17025 certification standards.
