Hair Follicle Drug Testing - Breaux Bridge, LA

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. Hair preserves a prolonged record of alcohol and drug use by capturing biomarkers in the strands of hair as they grow. When obtained near the scalp, hair can offer an approximately three-month detection period for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (around the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for screening and verification. For EtG, additional examinations, and/or tests exceeding 10 panels, a 150mg sample is advisable. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other types like facial and axillary hair.

Process Overview

The laboratory process for a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of processing a sample into the lab’s system. This step ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not covered by an electronic chain of custody system.

Screening provides a preliminary check for substance abuse. Although Screening is a cost-effective method to rule out drug use for most samples, a positive screen must be confirmed to be legally admissible. Samples that yield a presumptive positive result during Screening need secondary confirmation.

When a Screening yields a presumptive positive outcome, more hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are drawn out from the hair in much lower concentrations than other methods (such as urine or oral fluids), making hair drug screening a challenging methodology to perform.

Confirmation of any positive results from screening uses GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash before confirmation as needed. The complete lab process from Accessioning to Confirmation undergoes review following both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests identify drug consumption for up to 90 days, whereas urine tests offer a shorter detection timeframe.
• High challenge to alter results: Cheating a hair drug test is exceptionally challenging, enhancing result precision.
• Historical data provision: It delivers a long-term pattern of drug use, not just immediate consumption.

Limitations:

• Recent use undetectable: Drugs take roughly 5-7 days to become traceable in hair.
• Expense: Hair drug tests generally exceed the cost of other drug testing methods.
• Result variation: Variables such as hair color and individual growth differences can affect drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests", this test examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Breaux Bridge, LA, hair follicle testing often surpasses traditional urine tests in effectiveness.

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.
