Hair analysis is now viewed as a significant method for identifying drug and alcohol consumption. Hair captures a long-term history of alcohol and drug use by embedding biomarkers within the strands of the growing hair. When harvested near the scalp, hair offers up to about a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample length of 1.5 inches, with roughly 200 hair strands (about the diameter of a #2 pencil) closest to the scalp, yields 100mg of hair, considered the optimal sample size for testing and confirming. For EtG, add-ons, and/or more comprehensive tests exceeding 10 panels, a sample of 150mg is ideal. It is suggested to weigh the sample using a jeweler's scale. If scalp hair cannot be provided, a corresponding quantity of body hair may be used. References to head hair denote scalp hair specifically. Body hair encompasses all other hair types (facial, underarm, etc.).
Process Overview
The fundamental steps in lab processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the procedure of integrating a sample into a lab's system. It entails checking that the sample is sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.
Screening is a preliminary examination for substance abuse. Although Screening is an economical method for eliminating drug use in most cases, a positive outcome necessitates confirmation to be legally permissible. Samples that show a potential positive in Screening require follow-up confirmation.
If Screening indicates a potential positive result, additional hair is retrieved from the initial sample and prepared for Extraction. In this phase, the substances are isolated from hair at concentrations lower than those in other tests (e.g., urine or oral fluid), making hair testing the most challenging technique to administer.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples identified as potentially positive undergo washing before confirmation when needed. The comprehensive lab procedure, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
