Hair assessments now stand recognized as a potent method for identifying the consumption of drugs and alcohol. Hair captures a long-lasting record of alcohol and drug intake by embedding biomarkers within the fibers of a developing hair shaft. When taken close to the scalp, hair delivers an approximate 3-month window for the detection of alcohol and drugs. Hair is straightforward to collect, relatively tough to tamper with, and simple to transport.
A 1.5-inch segment containing roughly 200 strands of hair (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, forming the optimal sample for analysis and confirmation. For EtG, auxiliary tests, or those exceeding 10 panels, 150mg of the sample is advised. Measurement of the sample on a jeweler’s scale is suggested. If scalp hair is not present, a comparable quantity of body hair may be used. References to head hair imply scalp hair specifically. Body hair encompasses any other types (facial, axillary, etc.).
Process Overview
The primary components in the laboratory procedure for processing a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning concerns the initial integration of a sample into a laboratory’s system. The process ensures the sample was adequately sealed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any data entry not handled by an electronic chain of custody system.
Screening constitutes a preliminary swift assessment for substances of abuse. Screening is economical for eliminating drug usage in most samples; however, a positive screen must be validated for court admissibility. Samples deemed potentially positive in Screening necessitate further confirmation.
If Screening suggests a sample is positive, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated from hair at concentrations considerably lower than other methods (like urine or oral fluid), underlining why hair drug assessments are among the toughest methodologies.
GC/MS, GC/MS/MS or LC/MS/MS verify all positive screening findings. Each presumably positive sample is cleansed before confirmation as necessary. The lab process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
