Hair analysis serves as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of drug and alcohol use by embedding biomarkers within the hair strand's fibers as it grows. When taken near the scalp, hair can reveal a detection window of up to around 3 months for alcohol and drug use. Hair is easy to gather, challenging to tamper with, and straightforward to transport.
A sample size of 1.5 inches consisting of approximately 200 hair strands (resembling the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal sample for initial and confirmatory tests. For EtG, add-ons, or tests beyond 10 panels, 150mg of the sample is suggested. We advise using a jeweler’s scale to weigh the sample. If scalp hair is not present, an equivalent amount of body hair can be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the lab's system. This process confirms the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finishes any further data entry not completed by an electronic chain of custody system.
Screening executes a preliminary rapid check for illicit substances. While Screening economically dismisses drug use in most samples, a positive result on the screen requires confirmation for court acceptance. All samples with presumptive positive results in Screening necessitate secondary confirmation.
For samples showing presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. This phase involves removing drugs from the hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), highlighting why hair drug analysis is the most intricate methodology.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are washed prior to confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
