Hair Follicle Drug Testing - Cumberland, MD

What it is, How it works

Hair analysis is increasingly regarded as a robust method for identifying drug and alcohol consumption. Hair strands encapsulate long-term histories of alcohol and other substances by locking in biomarkers as the hair grows. Collected near the scalp, hair offers up to a roughly 3-month detection period for alcohol and drugs. Collection is straightforward, it is relatively resistant to tampering, and it ships easily.

A 1.5-inch portion of about 200 hair strands (approximately the width of a #2 pencil) nearest the scalp yields 100mg of hair, which is the preferred sample for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is suggested. We advise measuring the specimen's weight with a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be utilized. By "head hair," we specifically mean scalp hair, while "body hair" encompasses all other types (face, armpits, etc.).

Process Overview

The laboratory examination of a drug test result unfolds in four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the commencement of processing a sample within a lab's system. This phase includes confirming that the sample was properly sealed and delivered, generating a random Laboratory Accessioning Number (LAN), and executing any additional data entry absent in an electronic chain of custody system.

Screening conducts a preliminary check for drug abuse. Although it is an economical means to eliminate drug usage in most samples, any positive result from Screening mandates further confirmation to be legally admissible. Samples marked as presumptive positive in Screening necessitate a follow-up confirmation.

If a sample tests as presumptively positive during Screening, more hair is extracted from the original specimen to prep for Extraction. This stage involves extracting drugs from hair at concentrations much lower than other methods (e.g., urine or oral fluid), hence making hair drug screening the most complex methodology.

Confirmation of any affirmative screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation, as needed. The complete lab process from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug use up to 90 days recurrently, unlike urine tests with a narrower detection window.
• Hard to manipulate: Altering a hair drug test is considerably challenging, enhancing the reliability of the results.
• Shows historical usage: Offers insights into a pattern of drug usage over a timeline, beyond mere recent consumption.

Limitations:

• Cannot notice recent ingestion: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests are often pricier than alternative drug testing methods.
• Result variations: Elements like hair color and individual hair growth variability can influence the concentration of drug metabolites in hair.

Note: Although referred to as "hair follicle tests," the evaluation assesses the hair strand rather than the follicle itself beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle and urine testing in Cumberland, MD, hair testing emerges as superior. It offers greater detection accuracy and reliability.

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.
