Hair testing has gained recognition as a significant method for uncovering drug and alcohol consumption. Hair acts as a long-term record of alcohol and other drugs by capturing biomarkers within the fibrous structure of growing hair strands. When obtained near the scalp, hair can reveal substance usage for approximately three months. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.
A 1.5-inch segment comprising roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for preliminary screening and confirmation. For EtG, additional assays, or more than 10-panel tests, a 150mg sample is suggested. We advise using a jeweler's scale to determine the specimen's weight. If scalp hair is absent, an equivalent quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into the laboratory system. This step includes confirming that the sample was correctly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and conducting any supplementary data entry not facilitated by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for drugs of abuse. While Screening offers a cost-efficient method to exclude drug use in most samples, a positive result requires confirmation for court admissibility. Any sample that tests presumptively positive in Screening necessitates a secondary confirmation.
Should a sample be presumptively positive at the Screening phase, additional hair is extracted from the initial specimen for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration compared to other methodologies (e.g., urine or oral fluid), underscoring the complexity of hair drug testing methodologies.
Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive are cleansed prior to confirmation if deemed necessary. The comprehensive laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
