Hair analysis has become recognized as an effective means for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by capturing biomarkers within the fibers of the hair shaft. When cut close to the scalp, hair can reveal up to a three-month window of drug and alcohol usage. Hair is easy to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hair strands (about the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal amount for both screening and confirming. For additional EtG, extended panels, or examinations exceeding 10 panels, 150mg of the hair sample is advised. It's beneficial to measure the specimen using a jeweler’s scale. If head hair isn't available, an equivalent amount of body hair can be gathered. By "head hair," we mean scalp hair exclusively. "Body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is entered into the laboratory’s system. This step ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic chain of custody system.
Screening is a preliminary check for the presence of abused drugs. Although it is a cost-efficient way to eliminate drug usage for most samples, any positive screen must be confirmed for legal acceptability. Samples that test presumptively positive during Screening need a subsequent confirmation.
If Screening yields a presumptive positive, additional hair is extracted from the original sample and prepped for the Extraction phase. In this step, drugs are pulled from the hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging methodologies.
Confirmation of any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing before confirmation if necessary. The entire process from Accessioning to Confirmation is conducted in compliance with both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
