Hair Follicle Drug Testing - Fork Union, VA

What it is, How it works

Hair examinations are increasingly regarded as a robust mechanism for identifying drug and alcohol consumption. Hair captures enduring records of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When sourced near the scalp, hair offers a detection span extending up to roughly three months for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.

A 1.5-inch snippet comprising roughly 200 strands of hair (akin to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, deemed the optimal sample for both screening and confirmation. For tests like EtG, add-ons, and those exceeding 10 panels, 150mg is advisable. We suggest using a jeweler's scale for weighing the sample. If scalp hair is not an option, the same amount of body hair can be gathered. Mention of head hair pertains exclusively to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The core procedures in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into a lab’s system. This step confirms proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any further data input absent in an electronic chain of custody arrangement.

The Screening stage is a preliminary rapid assessment for drug abuse. While it's a budget-friendly method to exclude drug use in most samples, any positive screening must be authenticated for court acceptance. Samples with presumptive positives in Screening necessitate subsequent confirmation.

Should a sample exhibit a presumptive positive during Screening, more hair is extracted from the initial sample for Extraction. In this process, drugs are extracted from hair at much lower concentrations than other techniques (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of positive screening results leverages GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples showing presumptive positives undergo cleansing before confirmation if needed. The entire process, from Accessioning to Confirmation, undergoes scrutiny according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug assays can trace drug usage for up to 90 days, unlike urine assessments with shorter windows.
• Hard to falsify: Cheating a hair drug test is quite challenging, enhancing the accuracy of results.
• Delivers historical insight: It maps a timeline of drug use encompassing a span, not just recent consumption.

Limitations:

• Incapable of detecting recent use: Detecting drugs in hair necessitates around 5-7 days post-consumption.
• More costly: Hair drug evaluations are typically pricier than other drug testing approaches.
• Result fluctuations: Aspects like hair pigment and individual hair growth variability can influence drug metabolite concentration in hair.

Note: Often termed "hair follicle tests", this examination analyzes the hair strand rather than 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. 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.
