Hair Follicle Drug Testing - Litchfield, MN

What it is, How it works

Hair assessments are recognized as a compelling instrument for identifying drug and alcohol consumption. Hair captures a prolonged history of such substances by embedding biomarkers within the hair strand as it grows. When collected near the scalp, hair can offer a detection period of up to roughly three months for alcohol and other drugs. Collection is straightforward, relatively hard to tamper with, and convenient to transport.

A sample measuring 1.5 inches of approximately 200 hair strands (comparable to the girth of a #2 pencil) closest to the scalp will yield 100mg of hair, regarded as the optimal amount for tests and verification. For EtG, additional tests, and/or analyses exceeding 10 panels, a quantity of 150mg is advised. We suggest measuring the specimen using a jeweler’s scale. If scalp hair isn't accessible, an equivalent quantity of body hair may be obtained. When referring to head hair, we mean scalp hair solely. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four core stages in laboratory handling of a drug test output are Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the initial incorporation of a sample into a lab's system. This covers confirming the sample was correctly sealed and dispatched, assigning an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any further data input not covered by an electronic chain of custody arrangement.

Screening serves as a preliminary rapid assessment for drug misuse. Although Screening is affordable and effective in dismissing drug usage in most samples, a positive result needs confirmation for use in legal proceedings. Samples with a presumptively positive result in Screening necessitate secondary confirmation.

If a sample is identified as presumptively positive during Screening, additional hair is drawn from the primary specimen and processed for Extraction. Here, drugs are withdrawn from hair at significantly reduced concentration compared to other techniques (e.g., urine or oral fluid), which makes hair drug evaluation the most challenging methodology to execute.

Verification of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if required. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which offer a limited detection window.
• Resistance to manipulation: It's exceedingly difficult to falsify a hair drug test, ensuring greater accuracy in results.
• Offers usage trends: It can reveal a history of drug use over time, not merely recent consumption.

Limitations:

• Inability to spot recent use: It requires roughly 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests tend to be costlier than other drug testing techniques.
• Result variability: Aspects such as hair color and individual hair growth differences can impact the level of drug metabolites in hair.

Note: Though commonly termed as "hair follicle tests", the procedure assesses 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.
