Hair Follicle Drug Testing - Iberville, LA

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. The advantage lies in hair's ability to retain a long-term history by embedding biomarkers within the fibers of the hair strand as it grows. When harvested near the scalp, hair can offer a detection timeframe of up to roughly 3 months for alcohol and drugs. Collection is straightforward, tampering is challenging, and transportation is convenient.

A 1.5-inch portion, approximately 200 hair strands (comparable to a #2 pencil in thickness) nearest to the scalp, yields 100mg of hair, which is the preferred sample size for analysis and confirmation. For EtG, add-ons, and/or assessments beyond 10 panels, 150mg of the sample is advised. The use of a jeweler’s scale is suggested for measuring the specimen. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. References to head hair pertain solely to scalp hair, whereas body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result is divided into four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing phase, integrating the sample into the laboratory’s system. It involves confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry tasks not covered by an electronic chain of custody system.

Screening is a preliminary examination to identify potential drug use. While Screening is an economical method to rule out drug presence in most samples, a positive screen requires confirmation to be legally permissible. Any samples that yield a presumptive positive outcome in Screening necessitate secondary verification.

In case a sample yields a presumptive positive result during Screening, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are extracted from hair at a much lesser concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Verification of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed if necessary. The entire laboratory process, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which cover a shorter period.
• Resistance to tampering: Cheating a hair drug test is highly challenging, enhancing the accuracy of results.
• Historical usage data: It offers a retrospective pattern of drug use rather than merely recent consumption.

Limitations:

• Lacks detection of recent use: Drugs take about 5-7 days before they become detectable in hair.
• Expense: Hair drug tests are typically more costly than other drug testing techniques.
• Variability in outcomes: Elements like hair color and individual differences in hair growth can impact the presence of drug metabolites in hair.

Note: Despite the common term "hair follicle tests," the analysis is conducted 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.
