Hair Follicle Drug Testing - Garrison, MN

What it is, How it works

Hair testing is now recognized as an effective method for detecting drug and alcohol usage. By embedding biomarkers within the growing hair shaft, hair offers a long-term record of alcohol and drug consumption. When cut close to the scalp, hair can offer a detection timeframe of up to three months for both alcohol and other substances. Hair is easy to gather, resistant to tampering, and straightforward to transport.

A sample measuring 1.5 inches with about 200 hair strands (comparable to a #2 pencil diameter) near the scalp will yield 100mg of hair, which is ideal for analysis and confirmation. For EtG, additional testing, and/or tests exceeding 10 panels, a specimen quantity of 150mg is advised. It's best to weigh the sample on a jeweler’s scale. If head hair isn't an option, a comparable amount of body hair might be collected. Here, head hair refers exclusively to scalp hair, while body hair includes various other types (facial, axillary, etc.).

Process Overview

The laboratory handling of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial task of integrating a sample into a lab's system. This involves confirming the sample's proper sealing and transit, assigning a unique LAN (Laboratory Accessioning Number), and finishing any extra data input absent from an electronic chain of custody system.

Screening entails a swift preliminary assessment for substance misuse. While Screening provides an economical approach to dismiss drug usage in most cases, a positive screen must be validated to ensure court acceptance. Any samples that screen positive initially need further confirmation.

When a sample tests positive at the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. At this stage, drugs are extracted from hair at substantially lower densities than alternative methods (e.g., urine or saliva), highlighting why hair drug testing is notably challenging.

Validation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS technology. Presumptive positive samples undergo cleansing prior to confirmation as warranted. The entire lab sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can trace drug use for up to three months, unlike urine tests that provide a shorter detection range.
• High difficulty to manipulate: Hair drug examinations are tough to deceive, ensuring greater result accuracy.
• Offers historical insights: It reveals a timeline of drug usage over an extended period, not merely recent intake.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug analyses are typically pricier than other drug testing approaches.
• Result variability: Elements like hair hue and personal hair growth variations can influence the level of drug metabolites in hair.

Note: Although often mislabeled as "hair follicle tests", the examination targets the hair shaft, not the root 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.
