Hair testing is now recognized as a potent technique for identifying drug and alcohol consumption. The hair retains long-term indicators of substance use by embedding biomarkers into the hair strand's fibers as it grows. If gathered near the scalp, hair can offer a detection period of up to three months for detecting alcohol and other substances. Hair sample collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to a #2 pencil’s thickness) taken nearest to the scalp will yield 100 mg of hair, which is optimal for both screening and confirmation. For EtG, supplementary analyses, and/or tests exceeding 10 panels, it’s advised to use 150 mg of the sample. We suggest measuring the sample on a jeweler's scale. If scalp hair isn’t available, an equivalent portion of body hair can be gathered. When we mention head hair, we mean scalp hair solely. Body hair includes all other types (like facial, axillary, etc.).
Process Overview
The four principal stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a specimen into the lab’s system. This process encompasses verifying that the specimen was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional information not supplied via an electronic chain-of-custody system.
Screening involves an initial swift assessment for illicit drugs. Though Screening is a cost-efficient method to exclude drug use for most samples, any positive screen must be confirmed to be legally acceptable. All samples that are tentatively positive in Screening necessitate a follow-up confirmation.
Should a sample show tentative positivity during the Screening phase, more hair is extracted from the original sample for preparation for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid), which explains why hair drug testing presents the most intricate methodology.
Confirmation of any positive Screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing prior to confirmation when needed. The entire lab procedure from Accessioning to Confirmation is examined under the guidelines of both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
