Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. It can capture a historical record of substance use by embedding biomarkers within the strands as they grow. When hair is taken near the scalp, it can unveil up to a 3-month detection period for alcohol and drugs. It is easy to collect, tough to tamper with, and simple to transport.
A sample measuring 1.5 inches, comprising roughly 200 hair strands (about the thickness of a #2 pencil) close to the scalp provides 100mg of hair, the preferred amount for analysis and verification. For EtG and additional examinations exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale for exact measurement. If scalp hair can't be obtained, the same amount of body hair is acceptable. "Head hair" strictly refers to scalp hair, whereas "body hair" indicates every other hair type (facial, axillary, etc.).
Process Overview
There are four primary steps in the lab processing of a drug testing result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake process of a sample into a lab's database. It checks if the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and inputs supplementary data not captured by an electronic chain of custody system.
Screening is an initial swift examination for substances of abuse. While this is a cost-efficient method to eliminate drug presence in most samples, a positive result demands further verification for court admissibility. Those samples needing verification due to a positive screen require subsequent confirmation.
When a sample tests positive during Screening, additional hair is extracted from the original sample and prepped for Extraction. In this step, drugs are drawn from hair at lower concentrations than other methods (like urine or oral fluid), making hair drug screening the most challenging technique to execute.
Confirmation of any positive results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as necessary. The complete lab procedure from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards and meets accreditation standards ISO / IEC 17025.
