Hair Follicle Drug Testing - Tolchester, MD

What it is, How it works

Hair testing is recognized as a robust means for identifying drug and alcohol consumption. Hair holds an extended history of substance exposure by locking in biomarkers within the fibers of the developing hair shaft. When collected near the scalp, hair can reveal drug and alcohol use for roughly up to 3 months. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment consisting of about 200 hair strands (roughly comparable to a #2 pencil's width) nearest to the scalp yields 100mg of hair, which is the optimal sample mass for both screening and confirmation. For tests like EtG, additional panels beyond 10 require 150mg of the sample. We advise using a jeweler’s scale to measure the sample. If no scalp hair is available, a comparable amount of body hair can be used. "Head hair" specifically implies scalp hair, while "body hair" refers to all other types (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the primary stage where a sample is introduced into a laboratory’s system. This step ensures that the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry missing from an electronic chain of custody system.

Screening provides an initial rapid assessment for drug use. Although Screening offers a low-cost method to rule out drug use for most samples, any positive outcome requires confirmation for legal acceptance. Presumably positive samples from Screening need further verification.

For any sample deemed presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. At this stage, substances are derived from hair in concentrations notably lower than other methods (like urine or oral fluid), thereby making hair drug tests particularly challenging to execute.

The confirmation of positive screenings is executed via GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples that are presumptive positives undergo washing before confirmation if deemed necessary. From Accessioning to Confirmation, the entire laboratory workflow is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation in line with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests that feature a shorter detection timeframe.
• Difficult to manipulate: Manipulating a hair drug test is quite challenging, contributing to more reliable results.
• Historical insight: These tests offer an overview of drug use over time, rather than only recent usage.

Limitations:

• Incapable of spotting recent use: Drugs become detectable in hair about 5-7 days after use.
• Expense: Typically, hair drug testing costs more than other drug testing methods.
• Result inconsistencies: Variables like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Despite being termed as "hair follicle tests," the analyses target the hair strand itself, 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.

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.
