Hair testing has been recognized as a highly effective method for identifying drug and alcohol consumption. Hair serves as a timeline, capturing biomarkers within the strands over an extended period. When cut near the scalp, it offers a detection span of up to roughly three months. Hair is easy to obtain, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches comprising around 200 hair strands (about the width of a #2 pencil) near the scalp yields 100mg of hair, optimal for screening and confirmation. For EtG extensions and tests beyond 10 panels, 150mg of the sample is suggested. Using a jeweler’s scale is recommended for weighing the sample. If scalp hair is missing, an equivalent body hair volume can be used. The term "head hair" refers exclusively to scalp hair, while "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test outcomes comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a laboratory’s system. This process involves ensuring the sample was appropriately sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.
Screening performs a rapid assessment for substance abuse. Although Screening is a budget-friendly method to exclude drug usage in most samples, a positive screen necessitates confirmation for legal admissibility. Any samples presumptively positive in Screening need additional confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. In this stage, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screening.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo necessary washing before confirmation. The entire laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
