Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a detailed record of substances by embedding biomarkers within the fibers of the hair shaft as it grows. When collected near the scalp, this method provides a detection timeframe of up to about 3 months for both alcohol and drugs. Hair is straightforward to gather, comparatively resistant to tampering, and convenient to send.
A 1.5-inch portion of around 200 hair strands (equivalent to the diameter of a #2 pencil) closest to the scalp will yield 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, a specimen weighing 150mg is advised. It's suggested to use a jeweler’s scale to measure the specimen. If scalp hair isn’t available, an equivalent amount of body hair can be used. The term head hair refers specifically to scalp hair, while body hair encompasses all other varieties (such as facial or axillary).
Process Overview
The four primary stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab's system. This phase confirms the sample's proper sealing and shipping, allocates a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening performs an initial rapid assessment for substance abuse. Although cost-efficient, screening samples must undergo confirmation to be legally defensible in court. All samples that test presumptively positive during screening mandate secondary confirmation.
Upon a presumptively positive indicator during the Screening phase, additional hair is extracted from the sample for the Extraction phase. During Extraction, substances are isolated from hair in notably low concentrations compared to other methods (such as urine or oral fluid), accounting for the complexity of hair drug screening.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive specimens are cleansed prior to confirmation if required. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
