Hair Follicle Drug Testing - Deering, AK

What it is, How it works

Hair follicles are increasingly viewed as an effective means for identifying drug and alcohol consumption. By capturing biomarkers within the hair's growing strands, hair offers an extended history of substance use. Acquiring samples near the scalp can yield a detection span of roughly three months for alcohol and various drugs. Hair sampling is straightforward, relatively resistant to tampering, and simple to transport.

To secure an optimal sample for analysis and validation, collect a 1.5-inch segment of around 200 hair strands (about the thickness of a #2 pencil) from the scalp, totaling 100mg. For tests including EtG, additional panels beyond 10, a 150mg sample is advisable. It’s recommended to weigh the sample using a jeweler’s scale. If scalp hair isn't available, equivalent body hair can be used. The term ‘head hair’ specifically refers to scalp hair. In contrast, ‘body hair’ pertains to all other types, such as facial or axillary hair.

Process Overview

The drug test laboratory process incorporates four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary treatment of a sample within a laboratory's framework. This step ensures the sample's seal and shipment integrity, assigns a random Laboratory Accessioning Number (LAN), and finalizes any pending data entry absent from an electronic custody chain.

Screening acts as a preliminary evaluation for drug residues. While it's an economical approach for determining drug absence in many samples, a positive screening requires confirmation to hold legal standing. Samples indicating presumptive positivity in Screening necessitate further validation.

In cases of presumptive positives during Screening, additional hair is drawn from the original sample for the Extraction stage. Drugs are then isolated from hair in concentrations much lower than other methods (like urine or saliva), making hair screening a complex technique to execute.

GC/MS, GC/MS/MS, or LC/MS/MS methods are used to verify any positive screening outcomes. Presumptive positive samples undergo pre-confirmation washing if required. The entire process, from Accessioning through Confirmation, is evaluated following CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use up to 90 days, unlike urine tests with a shorter detection range.
• Resistance to manipulation: It's challenging to beat a hair test, resulting in higher accuracy of outcomes.
• Chronological data: It reveals patterns of drug consumption over time, not merely recent use.

Limitations:

• Cannot detect immediate use: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair tests generally incur higher costs than other drug tests.
• Result variability: Influences such as hair color and individual growth rates can impact drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests", the analysis actually focuses on 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
