Hair analysis is increasingly recognized for its efficacy in tracing substance use, including alcohol. Hair fibers archive a lengthy record of drug exposure by embedding biomarkers within the strands as they grow. When sourced near the scalp, hair offers an assessment period of roughly three months for detecting alcohol and various drugs. Collection is straightforward, tampering is challenging, and transport is uncomplicated.
A 1.5-inch section comprising around 200 hair strands (comparable to the diameter of a #2 pencil) nearest the scalp yields 100mg, the preferable quantity for both testing and verification. For EtG and tests exceeding 10 panels, a sample weight of 150mg is advisable. Utilizing a jeweler’s scale for measurement is suggested. In the absence of scalp hair, a commensurate quantity of body hair is an alternative. References to head hair specifically denote scalp hair, whereas body hair encompasses other types (e.g., facial, axillary).
Process Overview
The drug testing lab employs four primary processes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial integration of a specimen into the lab’s system. This entails confirmation of proper sample sealing and shipping, assigning it a unique LAN (Laboratory Accessioning Number), and completing any outstanding manual data entry that an electronic chain of custody system may lack.
Screening provides a preliminary analysis for drug contaminants. Although Screening efficiently eliminates drug presence in most cases, any positive detection requires subsequent validation for legal proceedings. Presumptively positive specimens identified in Screening necessitate confirmative testing.
Presumptively positive samples undergo further preparation during Extraction, involving additional hair from the initial sample set. Drugs in hair are isolated at concentrations notably lower than those in methods like urine or oral fluid testing. Consequently, hair drug screening poses a significant challenge.
Every positive result from the Screening process receives validation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned prior to Confirmation, if necessary. The laboratory process, from Accessioning to Confirmation, undergoes evaluation according to CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
