Hair analysis is now regarded as an effective means for identifying drug and alcohol consumption. Hair offers an extended retrospective view of substance use by encapsulating biomarkers within the growing hair strand's fibers. When taken near the scalp, hair can present up to nearly a three-month detection timeframe for alcohol and drugs. Hair sample collection is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch portion of roughly 200 hairs (comparable to a #2 pencil) nearest the scalp yields 100mg, which is optimal for screening and confirmation. For EtG tests, add-ons, and/or evaluations exceeding 10 panels, a 150mg sample is suggested. Using a jeweler’s scale for weighing the specimen is advisable. In the absence of scalp hair, a similar quantity of body hair might be acquired. 'Head hair' refers specifically to scalp hair, while 'body hair' pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into the laboratory's system. This process confirms that the sample packaging and shipment adhere to protocols, assigns a random LAN (Laboratory Accessioning Number), and finalizes any necessary data entry absent from an electronic chain of custody system.
Screening is a preliminary assessment for the presence of drugs of abuse. Though Screening offers a cost-efficient means of excluding drug use from most samples, positive outcomes necessitate confirmation for legal admissibility. Samples with presumptive positive results in Screening must undergo secondary verification.
Should a sample test presumptively positive in Screening, additional hair is extracted from the initial specimen for the Extraction phase. Here, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening notably challenging.
Confirmation of any positive results from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo necessary washes prior to confirmation. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.
