Hair Follicle Drug Testing - Hanley Falls, MN

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair offers an extended history of alcohol and drug exposure by trapping biomarkers within the growing hair's fibers. When sourced near the scalp, hair can reveal up to an estimated 3-month detection timeline for drugs and alcohol. It's easy to collect, resistant to tampering, and straightforward to mail.

A cluster of 1.5 inches consisting of about 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, the optimal sample for initial and confirmatory testing. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg sample is advised. We advocate using a jeweler’s scale to weigh the sample. In the absence of scalp hair, a corresponding amount of body hair is acceptable. By head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedures for processing a drug test result entail four core stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the preliminary processing of a sample into a lab’s database. This involves confirming that the sample is properly sealed and shipped, generating a unique LAN (Laboratory Accessioning Number), and completing any ancillary data entry absent in an electronic chain of custody set-up.

Screening signifies a preliminary rapid detection for drug abuse. Though Screening is an economical method to exclude drug presence in most samples, a positive result must be validated for legal admissibility. Samples that exhibit a presumptive positive in Screening mandate subsequent confirmation.

Should a sample show a presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are separated from hair at significantly lower concentrations compared to alternative methods (such as urine or oral fluid), making hair drug analysis the most complex method to execute.

Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed before confirmation as required. The complete lab procedure from Accessioning to Confirmation is scrutinized under the authority of both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug examinations can trace drug use up to 90 days, unlike urine tests with a shorter detection span.
• Resistance to tampering: Hair drug testing is very difficult to manipulate, enhancing result accuracy.
• Reveals usage history: It provides a historical consumption pattern over time, not just recent use.

Limitations:

• Incapable of identifying recent usage: It generally takes 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing often incurs higher costs than other testing techniques.
• Variability in outcome: Elements like hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Often labeled as "hair follicle tests", this assessment examines 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. 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.
