Hair Follicle Drug Testing - Barnes City, IA

What it is, How it works

Hair analysis has become recognized as a robust method for detecting drug and alcohol consumption. This method offers a comprehensive timeline of substance use by embedding biomarkers within the strands of hair as it grows. When obtained near the scalp, hair can capture up to a three-month period of substance use. Collecting hair is straightforward, somewhat resistant to tampering, and easy for transport purposes.

A 1.5-inch segment with roughly 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, the optimal quantity for screening and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. If scalp hair is not present, a comparable mass of body hair may be collected. When discussing head hair, it specifically indicates scalp hair. Body hair pertains to all other types, including facial and axillary hair.

Process Overview

There are four primary phases in the laboratory analysis of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This step involves verifying that the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry absent from an electronic chain of custody system.

Screening is an initial, swift evaluation for drug presence. Although Screening is a budget-friendly approach to dismiss drug presence in most samples, results showing drug presence must undergo confirmation to be valid in judicial settings. Samples testing presumptively positive during Screening require additional confirmation.

If a sample appears positive during the Screening phase, more hair is extracted from the original sample for the Extraction phase. This involves extracting drugs from hair at much lower concentrations compared to other sources (such as urine or oral fluid), underlining the complexity of hair drug screening.

Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suspected of being positive are cleaned before confirmation as necessary. The comprehensive lab process, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug tests can identify drug use for up to 90 days, while urine tests have a more limited detection range.
• Resistance to manipulation: Cheating a hair drug test is significantly challenging, enhancing result accuracy.
• Provides historical insight: It offers a timeline of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Variable outcomes: Differences such as hair color and personal hair growth rates can influence drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the examination is conducted on the hair strand itself, 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.
