Hair Follicle Drug Testing - Vienna Bend, LA

What it is, How it works

Hair analysis has established itself as an effective means for detecting substance use. By capturing biomarkers within the structure of the growing hair, it offers a comprehensive timeline of alcohol and drug consumption. When taken close to the scalp, hair can reveal substance use for up to three months. It is easy to collect, tough to tamper with, and simple to send for testing.

A 1.5-inch segment comprising around 200 hair strands (comparable to the size of a #2 pencil) next to the scalp yields 100mg of hair, optimal for both screening and confirmation. For EtG, additional procedures, or tests exceeding 10 panels, 150mg is suggested. Using a jeweler’s scale for measurement is recommended. If scalp hair is absent, equivalent body hair can be used. "Head hair" refers exclusively to scalp hair, while "Body hair" encompasses all other types (e.g., facial, axillary).

Process Overview

The key steps in lab processing for a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is integrated into the lab's workflow. This involves checking the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry required beyond an electronic chain of custody.

Screening entails a preliminary check for illicit substances. Although Screening efficiently eliminates drug use in most samples, a positive result must be confirmed for legal acceptance. Samples appearing positive in Screening need a further confirmation test.

Should a sample be positive in Screening, additional hair is sourced from the initial sample for Extraction. Drugs are derived from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis especially challenging to execute.

Any positive screening result undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are cleaned before confirmation as necessary. Each step, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug presence for up to 90 days, versus the shorter window of urine tests.
• Hard to alter: Cheating on a hair test is extremely tough, enhancing result reliability.
• Shows historical use: These tests can detail drug use trends over time, not just recent consumption.

Limitations:

• Cannot reveal recent use: Drugs may take about 5-7 days to become detectable in hair.
• Expense: Hair tests tend to be pricier than other testing methods.
• Result variability: Differences such as hair color and individual growth rates can impact drug metabolite levels in hair.

Note: The term "hair follicle tests" is often used, though the analysis actually focuses on the hair strand, not the follicle beneath the scalp

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.
