Hair analysis is recognized as an effective instrument for detecting substance and alcohol consumption. Hair captures a prolonged timeline of substance influence by embedding biomarkers within the hair strand's fibers as it grows. Hair, when gathered near the scalp, can offer close to a 90-day insight into substance and alcohol history. It's easy to obtain, relatively tamper-proof, and straightforward for transportation.
A collection of 1.5-inch segment from about 200 hair strands (roughly a #2 pencil's thickness) nearest the scalp results in 100mg, the perfect amount for analysis and validation. For EtG, additional panels, or tests extending beyond 10 panels, a 150mg sample is advised. It's best to assess the sample's weight using a jeweler's scale. If scalp hair is not accessible, a similar volume of body hair can be an alternative. When we mention head hair, it indicates scalp hair exclusively. Body hair includes all other varieties (e.g., facial, axillary, etc.).
Procedure Summary
The laboratory workflow for a substance test outcome includes four primary phases: Accessioning, Screening, Extraction, and Verification.
Accessioning entails the preliminary handling of a specimen within a lab's platform. This step ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing information not supplied by an electronic custody system.
Screening provides an initial rapid assessment for abused substances. Although Screening offers a cost-efficient means of excluding substance use in most cases, a positive outcome necessitates a Confirmation to be valid in legal situations. All presumptively positive screenings require follow-up confirmation.
Once a sample shows a presumptive positive in Screening, additional hair is taken from the starting sample for Extraction. During this phase, substances are isolated from hair at an even lower concentration than other methods (like urine or oral fluids), making hair substance analysis the most challenging technique to undertake.
Positive Screening results must be authenticated using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo cleansing before Confirmation if necessary. The complete lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
