Hair Follicle Drug Testing - Melrose, MT

What it is, How it works

Hair testing is recognized as an effective method for the identification of drug and alcohol consumption. By capturing biomarkers in the fibers of the growing hair strand, hair provides a long-term record of drug and alcohol use. When collected close to the scalp, it offers up to a 3-month window for detecting alcohol and other drugs. Hair collection is straightforward, resistant to tampering, and easy to transport.

A 1.5-inch hair sample consisting of about 200 strands (similar to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal amount for analysis and verification. For EtG, add-ons, and/or tests beyond 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the sample is recommended. In the absence of scalp hair, a similar amount of body hair can be used. "Head hair" specifically refers to scalp hair only, while "Body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The drug testing procedure in a laboratory involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the start of processing a sample within a lab’s system. It involves ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry omitted by an electronic chain of custody system.

Screening is a preliminary rapid test for drugs of abuse. Although it serves as an economical way to exclude drug use in most samples, a positive screen result requires confirmation to be valid in court. Any samples with a presumptive positive result in Screening necessitate additional confirmation.

If Screening indicates a presumptive positive, more hair is extracted from the original sample for the Extraction phase. During this stage, drugs are extracted at much lower concentrations compared to other methodologies (e.g., urine or oral fluid), highlighting the complexity of hair drug screening as a methodology.

Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use for up to 90 days, compared to the shorter detection period of urine tests.
• Challenging to counterfeit: It is notably hard to cheat a hair drug test, enhancing result reliability.
• Provides historical insight: It reveals a pattern of drug use over time, not merely recent use.

Limitations:

• Cannot catch recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Result variations: Aspects like hair color and individual growth differences can influence drug metabolite concentration in the hair.

Note: Often termed "hair follicle tests", the analysis focuses on the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Melrose, MT, hair follicle testing outshines urine testing due to several advantages. Accuracy and a longer detection period are critical benefits of hair testing.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
