Hair Follicle Drug Testing - Melvin Village, NH

What it is, How it works

Hair analysis is recognized as a formidable method for detecting drug and alcohol consumption. Hair chronicles the long-term use of substances by encapsulating biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can reveal up to about a 3-month detection period for substances like alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient for transport.

A hair sample of 1.5 inches, consisting of about 200 strands (similar in size to a #2 pencil) from the scalp provides roughly 100mg, which is the optimal amount for both initial and confirmatory testing. For EtG, extended tests, or panels over 10, 150mg is preferred. Using a jeweler’s scale to weigh the sample is advised. In the absence of scalp hair, an equivalent volume of body hair can be used. ‘Head hair’ refers specifically to scalp hair only, while ‘body hair’ encompasses other types such as facial or axillary hair.

Process Overview

The four fundamental stages in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is introduced to a laboratory’s system. This step ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not handled by an electronic chain of custody system.

Screening offers a preliminary assessment for drug abuse. Though cost-effective for negating drug usage in most samples, positive screenings must be validated to be acceptable in legal settings. Samples showing a presumptive positive in Screening necessitate a follow-up confirmation.

Presumptive positives from the Screening process lead to additional hair extraction for the Extraction phase. Here, drugs are pulled from hair at much lower levels compared to other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging method to conduct.

Confirmation of all positive results is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed before confirming when necessary. The entire cycle from Accessioning to Confirmation is vetted under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests trace drug usage for as long as 90 days, unlike urine tests with shorter detection durations.
• Challenging to falsify: Cheating on a hair drug test is exceedingly tough, leading to more precise results.
• Records historical usage: It provides a timeline of drug consumption over time, not solely recent use.

Limitations:

• Incapable of spotting recent use: Approximately 5-7 days are necessary for drugs to become traceable in hair.
• Cost implications: Hair drug tests typically cost more than other drug testing approaches.
• Result variability: Elements such as hair color and differences in individual hair growth may influence drug metabolite levels in hair.

Note: Although often termed as "hair follicle tests", the test evaluates the hair strand itself and not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
