Hair Follicle Drug Testing - Edgewater, MD

What it is, How it works

Hair testing is widely regarded as an effective method for identifying drug and alcohol consumption. The strands of hair provide a comprehensive history of substance use, as biomarkers are ensnared within the hair fibers as they grow. Hair that is gathered close to the scalp can offer a detection period of up to three months for alcohol and other substances. The collection of hair is straightforward, hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of roughly 200 strands of hair (equivalent to a #2 pencil's thickness) nearest to the scalp will yield approximately 100mg of hair, which is considered an ideal amount for testing and confirmation. For tests involving EtG, additional parameters, and panels exceeding ten, a sample of 150mg is advised. It's recommended to use a jeweler’s scale for accurate measurement. If scalp hair cannot be obtained, a comparable amount of body hair can be used. When discussing head hair, it refers specifically to scalp hair, whereas body hair encompasses all other types (such as facial or axillary).

Process Overview

The laboratory processing of drug test results involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the laboratory’s system. This stage includes confirming that the sample is sealed and transported correctly, allocating a unique LAN (Laboratory Accessioning Number), and entering any supplementary data not included in the electronic chain of custody.

The Screening process is used for an initial assessment for substances of abuse. Although this step is a cost-effective approach to eliminate drug usage in most samples, a positive result requires confirmation to be legally acceptable. Samples with presumptively positive results from Screening must undergo a further confirmation.

If a sample shows presumptive positivity during Screening, additional hair is taken from the initial collection for the Extraction stage. During Extraction, substances are retrieved from hair at substantially lower concentrations compared to other methods (such as urine or saliva); this makes hair drug screening a challenging methodology to execute.

For any positive screening outcome, Confirmation is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive undergo a washing process before confirmation as needed. The entire process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal substance use for up to 90 days, unlike urine tests which have a more limited detection window.
• Reduced chance of cheating: Cheating on a hair drug test is extremely challenging, enhancing the reliability of the results.
• Chronological usage data: This method offers a timeline of drug use, rather than just indicating recent use.

Limitations:

• Delayed detection: Drugs take around 5-7 days to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs compared to other testing types.
• Result variability: Elements such as hair color and individual hair growth patterns can alter drug metabolite concentrations in hair.

Note: While these tests are commonly termed "hair follicle tests", the analysis focuses on the hair strand itself, not the follicle located 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.
