Hair testing is recognized as an effective approach for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers within its growing strands. When acquired near the scalp, hair can reveal a drug use history of roughly 3 months. The process is uncomplicated, difficult to tamper with, and convenient for transportation.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (similar to a #2 pencil's thickness) nearest to the scalp, provides 100mg of hair, the optimal quantity for testing and verification purposes. To test for EtG, additional testing, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to measure the specimen with a jeweler’s scale. If scalp hair cannot be obtained, an equivalent amount of body hair could be used. "Head hair" exclusively refers to scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).
Process Overview
The process for laboratory analysis of a drug test comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample within the lab’s procedures. This step ensures the sample's proper sealing and transportation, generates a unique LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent from an electronic chain of custody system.
Screening involves an initial assessment for substance presence. Although Screening is a cost-efficient strategy to rule out drug presence in most samples, any positive findings necessitate confirmation to be legally valid. Samples with presumptive positive results at this stage require further verification.
When a sample tests presumptively positive during Screening, additional hair is withdrawn from the collected specimen and processed for Extraction. Here, substances are extracted from the hair at significantly lower concentrations compared to methods like urine or oral fluid analysis, making hair drug testing particularly challenging.
To confirm any positive screening outcomes, techniques such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. Presumptively positive samples undergo a cleansing process before confirmation if needed. The laboratory process from Accessioning through Confirmation adheres to CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
