Hair analyses are now regarded as a potent instrument for uncovering drug and alcohol use. Hair captures a historical record of alcohol and other substances by embedding biomarkers within the strands' fibers as they grow. When gathered near the scalp, hair can reveal use over up to three months for alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch portion of around 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp provides 100mg, the perfect amount for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is advisable. We suggest weighing the sample with a jeweler's scale. If scalp hair is not available, an equivalent volume of body hair can be obtained. By head hair, we mean scalp hair only, whereas body hair pertains to all other types (facial, armpit, etc.).
Process Overview
The four principal steps in processing a drug test at the lab encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary integration of a sample into a lab's system, ensuring the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry absent from the digital chain of custody system.
Screening conducts an initial swift assessment for drug abuse. Though Screening offers a cost-efficient method to rule out drug presence in most samples, any positive findings necessitate confirmation to stand in legal contexts. Samples preliminarily identified as positive during Screening must undergo secondary confirmation.
If a sample tests preliminarily positive during Screening, additional hair is extracted from the primary sample and prepared for Extraction. This phase involves extracting substances from hair at substantially reduced concentrations compared to other approaches (such as urine or oral fluids), rendering hair drug testing the most complex procedure to execute.
To confirm any positive screening outcomes, GC/MS, GC/MS/MS or LC/MS/MS are employed. All presumptively positive samples undergo washing prior to confirmation, as required. The comprehensive lab process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often called "hair follicle tests", the analysis actually examines the hair strand itself and not the follicle beneath the scalp.
