Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a history of alcohol and other drug use, capturing biomarkers within the fibers of the growing hair. When collected close to the scalp, it offers a detection window of up to three months for these substances. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A sample of 1.5 inches in length comprising around 200 hair strands (equivalent to the thickness of a #2 pencil) collected close to the scalp yields 100mg of hair, which is ideal for screening and confirmation. For EtG, add-ons, and/or more than 10-panel tests, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair be unavailable, the equivalent quantity of body hair can be collected. References to head hair specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The drug test laboratory process consists of four main steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the lab’s system. This step includes confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry if required by the electronic chain of custody system.
Screening offers a preliminary quick examination for drugs. Although cost-effective for excluding drug use in the majority of samples, a confirmed screen is necessary for court admissibility. Samples presumptively positive in Screening require secondary confirmation.
For samples showing presumptive positivity during Screening, additional hair is taken from the initial sample and prepared for Extraction. In this step, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug testing particularly challenging.
Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive findings are washed as required before confirmation. The entire process from Accessioning to Confirmation is evaluated under CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
