Hair Follicle Drug Testing - Elmo, TX

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. It captures a historical record of substance use by locking biomarkers within the developing hair strand fibers. When obtained near the scalp, hair can offer up to a 90-day detection duration for alcohol and other substances. The collection of hair is uncomplicated, relatively hard to tamper with, and easy to transport.

A 1.5-inch sample with around 200 hair strands (similar to a #2 pencil in size) nearest to the scalp yields 100mg of hair, ideal for analysis and validation. For EtG, additional tests, and screenings exceeding 10 panels, a 150mg sample is advisable. We suggest weighing the sample on a jeweler’s scale. If scalp hair is unavailable, equivalent amounts of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other types (like facial or axillary hair).

Process Overview

The four fundamental procedures in a lab’s drug test result processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into a laboratory’s system. It involves confirming that the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry not supplied by an electronic chain of custody framework.

Screening serves as an initial, swift evaluation for drugs of abuse. While Screening is a cost-efficient strategy to eliminate drug usage in the majority of samples, a positive result requires confirmation for court admissibility. Any samples presumed positive in Screening must undergo secondary confirmation.

If a sample tests positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted at far lower concentrations compared to other techniques (like urine or oral fluid), marking hair drug analysis as the most challenging to conduct.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if necessary. Every laboratory stage from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests recognize drug use up to 90 days, surpassing the detection window of urine tests.
• Minimal cheating potential: It is exceptionally challenging to deceive a hair drug test, enhancing result accuracy.
• Historical usage data: It reveals a usage trend over time, not just recent usage.

Limitations:

• Inability to detect recent usage: Drugs typically become detectable in hair approximately 5-7 days following use.
• Expense: Hair drug tests are often more costly than other drug testing methods.
• Result variations: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strand itself, not the hair 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.
