Hair Follicle Drug Testing - Dunn Loring, VA

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. It offers a prolonged history of substance use by capturing biomarkers in the fibers of hair as it grows. When gathered near the scalp, hair can show results for up to roughly three months for the use of alcohol and drugs. Collecting hair is straightforward, relatively tamper-resistant, and convenient to mail.

A sample taken from 1.5 inches of hair, consisting of approximately 200 strands (about the thickness of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is optimal for both initial and confirmation analysis. For testing EtG, additional analyses, or screenings exceeding 10 panels, a 150mg sample is advised. It is suggested to weigh the sample using a jeweler's scale. If head hair is not obtainable, an equal quantity of body hair may be used. Head hair refers exclusively to scalp hair, while body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The four primary phases in a laboratory's analysis of a drug test are Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample undergoes preliminary integration into a lab's system. This step involves confirming whether the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any outstanding data entry tasks the electronic chain of custody system hasn't covered.

Screening represents an initial swift assessment for drugs of abuse. Although Screening is an economical method to dismiss drug use for the majority of samples, a positive finding requires confirmation to be legally permissible. Any samples deemed presumptively positive during Screening demand further verification.

Should a sample test presumptively positive at the Screening phase, further hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at a much lower concentration level than in other practices (e.g., urine or oral fluid), marking hair drug screening as one of the most challenging methodologies to execute.

Confirmation for any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity undergo a cleansing before confirmation when necessary. The complete lab procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation, alongside accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing identifies drug use for up to 90 days, unlike urine tests which have a more limited detection timeframe.
• Hard to falsify: Hair drug testing is challenging to deceive, thus enhancing result accuracy.
• Shows usage patterns: It displays a drug usage trend over time, instead of merely recent consumption.

Limitations:

• Cannot show recent usage: Drugs typically take about 5-7 days to become detectable in hair.
• Higher expenses: Hair drug testing generally incurs more cost than alternative testing methods.
• Result inconsistencies: Hair color and individual hair growth differences can influence drug metabolite concentration levels in hair.

Note: Although often called "hair follicle tests", the assessment evaluates the hair 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.
