Hair testing has gained a reputation as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When hair is collected near the scalp, it can offer an approximate 3-month detection period for alcohol and other substances. Hair is straightforward to gather, relatively tough to tamper with, and easy to transport.
A sample measuring 1.5 inches, consisting of roughly 200 strands of hair (comparable to a #2 pencil in thickness) nearest to the scalp, will yield 100mg of hair, which is the optimal amount for both testing and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is suggested. Using a jeweler’s scale for weighing the specimen is advised. If scalp hair is absent, a similar quantity of body hair can be gathered. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other types, including facial and axillary hair.
Process Overview
The primary stages in lab processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial integration of a sample into a lab system. This entails checking if the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any missing data entry not handled by an electronic chain of custody system.
Screening provides a preliminary assessment for potential substance abuse. While Screening is a cost-effective method to eliminate drug use in most samples, a positive result necessitates confirmation for legal admissibility. Any samples with a presumptive positive result during Screening must undergo secondary verification.
For samples testing positive at the Screening phase, more hair is taken from the original sample for Extraction. This process extracts drugs from hair at much lower levels than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging procedure to execute.
Verification of positive Screening outcomes is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo washing before Confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
