Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. A hair sample offers a prolonged overview of substance intake by embedding biomarkers within the developing hair fibers. When taken close to the scalp, hair samples can reveal drug and alcohol presence for up to roughly three months. Hair collection is straightforward, fairly challenging to tamper with, and uncomplicated to transport.
A 1.5-inch segment consisting of approximately 200 hair strands (akin to the size of a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal amount for screening and verification. For EtG, supplemental tests, and/or analyses exceeding 10 panels, a collection of 150mg is advisable. We suggest weighing the sample using a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair can be gathered. References to head hair mean scalp hair exclusively. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a laboratory's system. This step confirms that the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening conducts an initial rapid check for illicit substances. Although Screening offers an economical method to dismiss drug consumption in most samples, a positive screen necessitates confirmation for legal admissibility. Samples showing presumptive positives in Screening require a subsequent confirmation.
In cases of a presumptive positive result during Screening, additional hair is extracted from the original sample for the Extraction process. Here, drugs are extracted from hair at a notably lower concentration compared to other techniques (e.g., urine or oral fluid), presenting the greatest difficulty in hair drug testing methodology.
Verification of any presumptive positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positives undergo washing before confirmation if needed. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Limitations:
