Hair Follicle Drug Testing - New Falcon, TX

What it is, How it works

The evaluation of hair samples has emerged as an effective means for identifying substance and alcohol consumption. Hair offers an extended timeline of drug and alcohol usage by assimilating biomarkers within the strands as they grow. When gathered near the scalp, hair can yield up to a three-month detection period for alcohol and drug substances. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A sample measuring 1.5 inches, with approximately 200 hair strands (roughly as thick as a #2 pencil) closest to the scalp, is needed to provide 100mg of hair, which is the standard quantity for evaluation and validation. For EtG, additional evaluations, and/or tests exceeding 10 panels, a 150mg specimen is suggested. Utilizing a jeweler’s scale for weighing the specimen is advised. If scalp hair isn't accessible, a comparable quantity of body hair can be obtained. When we mention head hair, we explicitly mean scalp hair. Body hair encompasses all other types (e.g., facial, axillary, etc.).

Process Overview

The core stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the preliminary processing of the sample into the lab's database. This step involves verifying proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from the electronic chain of custody record.

Screening entails an initial expedited verification for drugs of misuse. Though an efficient method to dismiss drug presence in most cases, any positive outcomes from Screening require further verification to be legally valid. Samples with tentative positive findings from Screening necessitate additional confirmation.

Upon obtaining a presumptive positive from Screening, additional hair is segmented from the original sample and readied for Extraction. This stage involves isolating drugs from hair at much reduced concentrations than in other methods (e.g., urine or oral fluid), thus making hair drug screening the most intricate technique to execute.

Validation of any positive screening result is performed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes undergo a washing process before validation as deemed necessary. The comprehensive lab process from Accessioning to Confirmation undergoes examination in line with the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug intake for up to 90 days, unlike urine tests which have a brief detection span.
• Challenging to manipulate: Cheating on a hair drug test is exceedingly difficult, enhancing result reliability.
• Conveys historical usage: It outlines a timeline of drug consumption over a period, not merely recent intake.

Limitations:

• Incapable of detecting recent intake: Detection of drugs in hair takes around 5-7 days post-consumption.
• Expense: Hair drug evaluations generally incur more costs than other testing methodologies.
• Result variability: Factors such as hair pigmentation and personal growth patterns can influence drug metabolite levels in hair.

Note: Although commonly termed "hair follicle tests", the assessment pertains to the hair fibers themselves, 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.
