The use of hair analysis has emerged as an effective method for detecting substance and alcohol consumption. Hair captures a long-lasting record by embedding biomarkers within its fibers as it grows. When taken near the scalp, hair can reveal substance and alcohol intake for up to a quarter of a year. Collecting hair is straightforward, hard to tamper with, and convenient for transportation.
A sample of 1.5 inches consisting of roughly 200 hair strands (approximately the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for analysis and validation. For EtG, additional tests, and tests exceeding 10 panels, a 150mg specimen is advised. It's recommended to measure the specimen using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair is an alternative. Reference to head hair pertains exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The essential stages in lab analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the fundamental processing of a sample into the lab's system, including verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.
Screening involves an initial rapid assessment for substance use. Screening is cost-efficient for ruling out drug intake on most samples; however, a positive result needs validation for court acceptability. Any samples assumed positive in Screening necessitate a subsequent confirmation.
If a specimen tests presumed positive in Screening, more hair is extracted from the initial sample and readied for Extraction. Here, substances are extracted from hair at a much lower concentration than in other methods (such as urine or oral fluids), accounting for the complexity of hair drug analysis.
Verification of any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation when necessary. Every step, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
