Recognized as a robust method for detecting substance use, hair testing reveals a timeline of drug and alcohol consumption by embedding biomarkers within the hair's fibers. When obtained adjacent to the scalp, this method can reveal drug and alcohol use for a span of nearly three months. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A hair sample measuring 1.5 inches with roughly 200 strands (comparable to the girth of a #2 pencil) near the scalp will weigh approximately 100mg, which is the optimal quantity for screening and confirmation processes. For tests that include EtG, additional testing, and/or exceed 10 panel tests, a 150mg sample is advised. We suggest using a jeweler’s scale to weigh the sample. In the absence of scalp hair, an equivalent amount of body hair can be collected. "Head hair" denotes only scalp hair, while "body hair" comprises other hair forms (such as facial and axillary hairs).
Process Overview
The four essential phases in the laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the preliminary processing of samples into the laboratory’s system. This step includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and filling out extra data entry absent from an electronic chain of custody system.
Screening serves as an initial swift evaluation for drugs of abuse. Even though Screening offers a cost-efficient measure to eliminate drug usage for the majority of samples, a positive screen demands confirmation to stand in court. Samples with a presumptive positive result during Screening necessitate secondary confirmation.
If a sample registers as presumptive positive at the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at a significantly diminished concentration compared to other methodologies (such as urine or oral fluid), positioning hair drug screening as the most intricate methodology to conduct.
Recognition of any positive screening result occurs via GC/MS, GC/MS/MS or LC/MS/MS. Samples registering presumptive positive undergo washing before confirmation as required. A comprehensive review of the laboratory process from Accessioning to Confirmation ensues under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly named "hair follicle tests," this evaluation inspects the hair strand, not the follicle beneath the scalp.
