Hair tests are recognized as a robust method for identifying substance and alcohol usage. Hair retains a comprehensive record of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When taken from near the scalp, it can reveal drug and alcohol use for up to about 90 days. Hair is straightforward to gather, somewhat challenging to tamper with, and convenient to dispatch.
Securing a 1.5-inch section with about 200 hairs (the thickness of a #2 pencil) nearest to the scalp offers 100mg of hair, which is ideal for testing and validation. For EtG, additions, and/or panels beyond 10, a 150mg sample is suggested. We suggest using a jeweler's scale to measure the hair. If scalp hair isn't available, a similar amount of body hair can be used. When mentioning head hair, we mean scalp hair solely. Body hair refers to all non-scalp hair (facial, axillary, etc.).
Process Overview
The key phases in processing a drug test result via the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the sample's entry into the lab's system. This step involves ensuring the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing extra information not already captured by an electronic chain of custody system.
Screening provides an initial swift assessment for substances of abuse. Although Screening offers a low-cost way to detect substance use in many samples, a positive screening must be verified to be acceptable in legal settings. Samples with presumed positives in Screening need a secondary verification.
For samples marked as presumably positive during Screening, more hair is drawn from the original collection and readied for Extraction. In this phase, substance extraction from hair occurs at much lower concentrations compared to other methods (such as urine or oral fluids), which is why hair drug testing is the most intricate method to conduct.
Verification of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing if necessary before confirmation. The full laboratory regimen, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standards.
