Hair Follicle Drug Testing - Paxton, MA

What it is, How it works

Hair analysis is recognized as a substantial method for identifying drug and alcohol use. Hair archives a substantial timeline of alcohol and substances by embedding biomarkers within the fibers of the developing hair strand. When procured near the scalp, hair can offer a detection window of up to roughly 3 months for alcohol and drugs. Collecting hair is uncomplicated, relatively challenging to tamper with, and simple to transport.

A hair segment of 1.5 inches comprising roughly 200 strands (comparable to the diameter of a #2 pencil) nearest to the scalp supplies 100mg of hair, which is optimal for analysis and validation. For EtG, supplementary tests, and/or evaluations beyond 10 panels, a 150mg sample is advised. It’s advisable to weigh the sample using a jeweler's scale. If scalp hair is absent, a comparable quantity of body hair might be utilized. References to head hair are specifically about scalp hair. Body hair alludes to other hair forms (facial, axillary, etc.).

Process Overview

The quartet of key stages in processing a drug test in the lab comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a specimen into a lab’s framework. This phase ensures the specimen was properly sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and fulfills any further data input absent in an electronic chain of custody system.

Screening encompasses an initial rapid assessment for drugs of abuse. While Screening economically eliminates substance use in most specimens, a positive screen necessitates confirmation to be valid in legal proceedings. Any specimens that are presumably positive in Screening require secondary confirmation.

For samples presumptively positive in Screening, additional hair is extracted from the initial sample and prepped for Extraction. During this phase, drugs are extracted from hair at a notably lower concentration than in other methods (e.g., urine or oral fluid), highlighting why hair drug analysis is the most complex procedure to achieve.

Validating any positive screening results occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo washing prior to confirmation as required. The comprehensive lab workflow from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair criterion and the accreditation to ISO / IEC 17025 norms.

Advantages of hair drug testing:

• Extended detection window: Hair drug evaluations can identify drug intake for up to 90 days, unlike urine tests with a shorter detection range.
• Challenge to deceive: It is significantly challenging to manipulate a hair drug test, rendering the outcomes more reliable.
• Provides retrospective data: It offers a usage pattern over time, surpassing merely recent usage identification.

Limitations:

• Inability to detect recent consumption: It requires approximately 5-7 days for drugs to be noticeable in hair.
• Expense: Hair analysis tests are usually higher priced than alternate drug testing methods.
• Result variability: Elements such as hair hue and individual hair growth differences may influence drug metabolite concentration in hair.

Note: Though commonly called "hair follicle tests", the test analyzes the hair strand instead of 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.
