Hair Follicle Drug Testing - Wallace Ridge, LA

What it is, How it works

Hair analysis has emerged as an effective means for identifying the usage of alcohol and drugs. Hair captures a prolonged record of substance intake, embedding biomarkers within the strands of hair as they grow. When sampled near the scalp, hair can reveal drug and alcohol use for up to three months. This method of testing is straightforward to gather, relatively challenging to tamper with, and convenient for mailing.

Collecting a 1.5-inch segment of around 200 hairs (approximately the width of a #2 pencil) from the scalp yields 100mg of hair, which is optimal for testing and verification. For EtG, supplementary tests, and analyses exceeding 10 panels, 150mg of hair is preferred. We advise using a jeweler’s scale to weigh the sample. If scalp hair is inaccessible, a similar amount of body hair can be used. By head hair, we mean scalp hair. Body hair includes all other types (facial, axillary, and so on).

Process Overview

The key steps in processing a test sample in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial setup of a sample within a lab system. It comprises ensuring the sample was securely sealed and sent, assigning it a unique LAN (Laboratory Accessioning Number), and performing any supplementary data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid analysis for potential drug misuse. While Screening offers a cost-efficient method to dismiss drug use in most samples, confirmation is required for legally binding results in any positive screen. Samples indicating potential positivity in Screening necessitate a secondary confirmation.

If Screening indicates a positive result, additional hair from the initial sample is prepared for Extraction. During this phase, drugs are retrieved from hair but at much lower concentrations compared to other methods (like urine or oral fluid), highlighting the complexity of conducting hair drug screening.

Confirmation of a positive screen is finalized using GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples that test presumptively positive are cleansed as part of the preparation for confirmation, if necessary. The complete laboratory sequence from Accessioning to Confirmation is evaluated against both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards.

Perks of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug usage for as long as 90 days, in contrast to urine tests which have a shorter detection timeframe.
• Hard to deceive: Hair drug tests are highly resistant to adulteration, ensuring reliable accuracy.
• Chronological usage insight: It provides a record of drug consumption over time, not merely recent use.

Drawbacks:

• Inability to detect recent intake: Drugs take about 5-7 days to appear in hair.
• Higher expense: Hair drug testing incurs greater costs compared to alternative testing methods.
• Result disparities: Variables like hair color and personal hair growth may influence drug metabolite concentrations in the hair.

Note: Despite often called "hair follicle tests", the evaluation focuses on the hair strand and 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.
