Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. The hair captures biomarkers within its fibers as it grows, offering a long-term overview of substance use. With collection near the scalp, hair can reveal drug and alcohol usage for up to roughly three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment containing about 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, suitable for testing. For EtG, extra analyses, and/or screenings beyond 10 panels, a 150mg sample is advised. It’s suggested to measure the specimen with a jeweler’s scale. If scalp hair isn't obtainable, an equivalent amount of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial incorporation of a sample into the laboratory system. This process ensures the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and finishes any required data entry that is missing from an electronic chain of custody system.
Screening provides a preliminary assessment for drugs of abuse. Though cost-efficient for ruling out drug use in most samples, a positive screening result requires confirmation for legal admissibility. Any samples that are presumably positive during Screening must undergo a further confirmation process.
If a sample indicates a presumptive positive in the Screening phase, additional hair is extracted from the original sample for further Extraction. During Extraction, substances are retrieved from the hair in much smaller quantities compared to other methods (e.g., urine or oral fluid), which is why hair drug testing is notably complex.
Confirmation of any positive screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives undergo necessary washing prior to confirmation. The full laboratory process from Accessioning to Confirmation undergoes review in line with both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
