Hair tests have become recognized as an essential method for spotting the use of drugs and alcohol. Hair offers a prolonged history of alcohol and drug usage by holding biomarkers in the fibers of the expanding hair strand. When taken near the scalp, hair can allow a roughly 3-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively tough to tamper with, and simple to transport.
A 1.5-inch specimen of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the prime sample for testing and verification. For EtG, additional assays, and/or screens surpassing 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jewelry balance. If scalp hair isn't obtainable, the same quantity of body hair can be used. When indicating head hair, we are referring solely to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a sample into a lab’s system. This process includes ensuring the sample was correctly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not included by an electronic chain of custody system.
Screening consists of an initial rapid assessment for substance misuse. While Screening is a cost-effective method to dismiss drug consumption in many cases, a positive screen must be verified to hold up in court. Samples that test presumptively positive in Screening require a secondary confirmation.
If a specimen tests presumptively positive in the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at a considerably lower concentration than other methods (such as urine or oral fluid), concluding hair drug screening as the most challenging method to execute.
Confirmation of any positive Screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptively positive specimen is cleansed before confirmation if necessary. The full lab process from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
