Hair Follicle Drug Testing - Warrensburg, IL

What it is, How it works

Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. Hair can offer a prolonged history of drug and alcohol patterns by encapsulating biomarkers within the strands of hair as they grow. Gathered near the scalp, hair can reveal a detection window of up to roughly 3 months for substance use. Hair is straightforward to collect, relatively tamper-resistant, and convenient to transport.

A sample measuring 1.5 inches, containing around 200 hair strands (roughly equivalent to a #2 pencil's width), will yield 100mg of hair, which is the optimal amount for both screening and confirmation purposes. For higher specificity tests like EtG, additional testing, or panels over 10, a 150mg sample is advised. Using a jeweler’s scale to measure the sample is recommended. If scalp hair is not accessible, an equivalent quantity of body hair can be used. 'Head hair' specifically refers to scalp hair alone, whereas 'body hair' includes all other hair types such as facial or axillary hair.

Process Overview

The drug test result processing in a laboratory entails four critical stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial handling of a sample within a laboratory's infrastructure. It comprises validating the correct sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and completing additional data entry not provided by an electronic chain of custody system.

Screening is an initial swift analysis for potential drug substances. While Screening is an economical means to exclude drug usage in the bulk of samples, any positive result requires confirmation for legal admissibility. Presumptively positive samples in Screening necessitate a further confirmation process.

Should a sample indicate a presumptive positive during Screening, more hair is extracted from the original sample to prepare for Extraction. At this phase, drugs are retrieved from hair at concentrations considerably lower than in other methods (e.g., urine or oral fluid), thus making hair drug screening the most challenging methodology to execute.

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

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use history for up to 90 days, in contrast to the shorter detection window of urine tests.
• Difficult to manipulate: Cheating a hair drug test is highly challenging, resulting in more reliable outcomes.
• Historical insight: It provides a timeline of drug usage over an extended period, not solely recent consumption.

Limitations:

• Cannot identify recent use: Drugs require approximately 5-7 days post-consumption to be detectable in hair.
• Cost implications: Hair drug tests typically incur higher costs compared to other testing methods.
• Result variability: Hair color and personal hair growth differences can impact drug metabolite levels in hair.

Note: While frequently termed "hair follicle tests", the analysis targets the hair strand and 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.
