Hair analysis has emerged as a vital technique for detecting drug and alcohol consumption. It offers an extensive record of drug and alcohol usage by capturing biomarkers within the fibers of expanding hair strands. When hair is collected near the scalp, it can reveal drug and alcohol use for a timeframe of up to about 3 months. This method is easy to conduct, hard to tamper with, and straightforward to transport.
A sample measuring 1.5 inches with roughly 200 hair strands (approximately the diameter of a #2 pencil) cut nearest the scalp provides 100mg of hair, considered optimal for testing and verification. For tests such as EtG, extensions, or those exceeding 10 panels, 150mg of the specimen is advisable. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a similar amount of body hair can be used in its place. "Head hair" specifically denotes scalp hair only, while "body hair" includes all other types (like facial, axillary, etc.).
Process Overview
The primary steps in the laboratory procedure for processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial procedure of integrating a sample into the lab’s workflow. This involves confirming the sample's sealing and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any further data entry omitted by an electronic chain-of-custody system.
Screening consists of a preliminary examination for potential drug abuse. While Screening efficiently eliminates drug use in most cases, a positive result requires confirmation for legal acceptance. Samples indicated as presumptively positive through Screening must undergo further verification.
Should a sample test positive during the Screening phase, additional hair is extracted from the original sample for the Extraction stage. Here, drugs are derived from the hair at a significantly reduced concentration compared to other practices (e.g., urine or oral fluid), explaining why hair drug testing is notoriously intricate.
Positive outcomes from Screening are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive samples are cleansed before confirmation where necessary. The laboratory process, from Accessioning through to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair regulations and ISO / IEC 17025 accreditation standards.
