Hair Follicle Drug Testing - Braddock Heights, MD

What it is, How it works

Hair testing is regarded as a potent method for identifying drug and alcohol usage. Hair captures a long-term record of alcohol and drug consumption by securing biomarkers within the fibers of its growing strands. When cut close to the scalp, hair provides a window of detection of approximately three months for alcohol and other substances. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.

A sample measuring 1.5 inches of roughly 200 strands of hair (around the width of a #2 pencil) near the scalp yields 100mg, which is the ideal amount for screening and confirmation. For EtG, additional tests, and/or panels over 10, a specimen of 150mg is suggested. It's advised to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, an equal amount of body hair can be collected. When referring to head hair, it strictly pertains to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning is the first step, incorporating a sample into the lab’s system. This step ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not available through an electronic chain of custody.

Screening is a preliminary assessment to identify drugs of abuse. Although it's a cost-effective measure for ruling out drug use in most samples, a positive screen requires confirmation to be recognized in legal proceedings. Any presumptively positive samples in Screening need further confirmation.

If a presumptive positive result arises during Screening, additional hair is extracted from the initial specimen for the Extraction phase. Here, drugs are extracted from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a highly complex technique to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing, as necessary, before confirmation. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for as long as 90 days, as opposed to urine tests which have a shorter detection span.
• Difficulty in manipulating results: Cheating on a hair drug test is challenging, thus enhancing result accuracy.
• Historical data provision: It delivers a usage pattern over time, not just recent drug use.

Limitations:

• Incapable of spotting recent usage: Drugs require approximately 5-7 days to become detectable in hair.
• Cost consideration: Hair drug tests tend to be pricier compared to alternative testing techniques.
• Result variability: Factors such as hair color and personal growth variations can influence drug metabolite concentrations in hair.

Note: While often termed "hair follicle tests," this test analyzes the strand, 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.
