Hair analysis is now acknowledged as a robust method for identifying substance usage. Hair strands capture biomarkers within their fibers, providing a chronicle of alcohol and drug consumption. When taken close to the head, hair can offer an approximate 3-month detection period for alcohol and other drugs. Collection of hair is straightforward, relatively hard to tamper with, and convenient to transport.
A 1.5-inch hair strand collection, about 200 strands or the thickness of a #2 pencil, equates to 100mg, the optimal sample for screening and validation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is advised. Utilizing a jeweler's scale for specimen measurement is recommended. Should scalp hair be inaccessible, an equivalent body hair amount can be collected. Reference to head hair specifically pertains to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses initial sample processing in a lab's system. It includes ensuring proper sealing and shipment of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any additional data input absent from an electronic chain of custody system.
Screening involves a preliminary assessment to detect substances of abuse. Despite Screening being cost-efficient for excluding drug use in most samples, positive results necessitate further confirmation for legal admissibility. Samples showing presumptive positives in Screening demand secondary verification.
In the presence of a presumptive positive during Screening, additional hair is drawn from the initial sample and readied for Extraction. This stage involves extracting drugs from hair at a significantly lower concentration than other methods (e.g., urine or oral fluids), justifying hair drug testing as the most challenging methodology.
Verification of any positive screening outcome occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positives undergo washing if necessary. The full laboratory procedure from Accessioning through Confirmation is scrutinized per the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 standard accreditation.
