Considered a robust method for identifying drug and alcohol presence, hair testing offers a comprehensive long-term analysis by capturing biomarkers within the strands. Hair obtained near the scalp can yield a detection window extending up to roughly three months for substances. The collection process is straightforward, the potential for alteration is minimal, and the shipping process is uncomplicated.
A 1.5-inch segment consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal quantity for evaluation and validation. For tests including EtG, additional substances, and those surpassing 10 panels, 150mg is advisable. We suggest weighing the hair sample on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent volume of body hair may be used. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses other types like facial or axillary hair.
Process Overview
The laboratory drug test result processing involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes integrating a sample into a lab’s system. This step assures the sample’s proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and fulfills any additional data entry lacking in an electronic chain of custody system.
Screening offers an initial swift examination for substance abuse. Despite being a cost-effective means to dismiss drug usage in most samples, a positive screen requires validation to be court-admissible. Any probable positive outcomes in Screening necessitate a follow-up confirmation.
For samples marked as presumptively positive during Screening, further hair is extracted from the original sample and readied for Extraction. At this phase, drugs are retrieved from hair at significantly lower concentrations compared to other methods like urine or oral fluid, underscoring the complexity of hair drug screening.
Confirmation for any presumptive positive result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptively positive samples undergo washing as needed. The entire process from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 accreditation standards.
