The utilization of hair testing has become an esteemed method for identifying drug and alcohol consumption. Hair serves as a prolonged archive of alcohol and drug intake by encapsulating biomarkers within the threads of the hair as it grows. When collected from near the scalp, hair can present up to a three-month timeline for detecting alcohol and other substances. Hair collection is straightforward, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the perfect quantity for analysis and confirmation. For EtG, additional testing, and/or examinations exceeding ten panels, 150mg of hair is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair isn't accessible, a similar volume of body hair can be gathered. When mentioning head hair, we specify scalp hair exclusively. Body hair pertains to any other hair types (facial, axillary, etc.).
Process Overview
The comprehensive procedure in the laboratory assessment of a drug test includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the primary integration of a sample into a laboratory’s database. This step verifies that the sample was precisely sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any further data entry absent in an electronic chain of custody interface.
Screening performs an initial rapid detection for illicit substance use. Though Screening is an economical means to eliminate drug consumption for most specimens, a positive screening requires validation to be accepted legally. Samples that indicate a likely positive result in Screening necessitate a subsequent confirmation.
In cases where a sample suggests a positive result in the Screening phase, additional hair is retrieved from the initial sample for Extraction. During this stage, substances are extracted from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most complex technique to execute.
Confirmation of any positive screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation whenever necessary. The entire laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO/IEC 17025 standards.
