Hair Follicle Drug Testing - Hebron, TX

What it is, How it works

Hair examination is increasingly recognized as an effective method for identifying drug and alcohol consumption. The hair fiber stores a prolonged history of alcohol and drug exposure by embedding biomarkers within the hair itself. When taken near the scalp, a hair specimen offers around a three-month window for identifying alcohol and drugs. Hair collection is straightforward, tampering is challenging, and the sample is simple to transport.

A sample of 1.5 inches consisting of roughly 200 hair strands (approximately equivalent to a #2 pencil's thickness) from the scalp provides a 100mg sample, suitable for analysis and confirmation. For EtG, additional tests, or tests encompassing more than 10 panels, a 150mg sample is advised. Measuring the sample's weight with a jeweler’s scale is suggested. If scalp hair cannot be obtained, a similar quantity of body hair is usable. "Head hair" specifically denotes scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).

Process Overview

The crucial stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a specimen into the lab's protocol, ensuring the sample's sealed and delivered status is checked, a LAN (Laboratory Accessioning Number) is allotted, and any extra data entry absent in an electronic chain of custody is completed.

Screening encompasses a preliminary analysis for substance abuse markers. Although an economical approach for precluding drug usage in most cases, any positive screen needs confirmation for legal acceptance. Samples suspected of being positive during Screening necessitate further confirmation.

Should a Screening indicate a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. In this phase, drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluids), underscoring why hair drug testing presents greater complexity.

Confirmation of confirmed positive results is executed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicating presumptive positivity undergo cleaning before final confirmation if required. The full laboratory operation from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) standards for Hair and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Drug use can be identified for up to 90 days with hair tests compared to shorter periods for urine tests.
• Challenging to manipulate: Hair drug tests are notably difficult to alter, enhancing accuracy.
• Reports historical usage: It charts drug use trends over time, beyond immediate usage.

Limitations:

• Inability to detect new usage: A delay of 5-7 days is typical for drug traces to become evident in hair.
• Expense: Hair testing generally incurs higher costs compared to other drug tests.
• Result variability: Hair color and growth differences can influence drug metabolite levels in hair.

Note: Referred to as "hair follicle tests", the evaluation targets 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
