Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a prolonged history of substance exposure. Collected near the scalp, it can reveal drug and alcohol presence over a period of up to 3 months. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section of approximately 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp yields about 100mg, which is the optimal amount for evaluation and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advisable. Utilizing a jeweler’s scale is suggested for accuracy. If head hair isn't accessible, a comparable volume of body hair can be utilized. When mentioning head hair, we refer specifically to scalp hair. Body hair includes all other hair types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result includes four main stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a sample into a lab's system. This step involves ensuring the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and performing any necessary data entry absent from electronic custody systems.
Screening provides an initial assessment for unauthorized substance use. Although a cost-effective method to eliminate drug use in most samples, a positive screen must be authenticated for legal admissibility. Samples that test presumptively positive during Screening require subsequent confirmation.
When a sample shows presumptive positivity in Screening, additional hair is processed from the original specimen for Extraction. During this phase, drugs are retrieved from hair with significantly lower concentrations than alternative methods (such as urine or oral fluids), which accounts for the complexity of hair drug examinations.
The confirmation of a positive result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation where needed. The full laboratory process from Accessioning to Confirmation complies with both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
