Hair Follicle Drug Testing - Vermont, WI

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers, offering a long-term record of substance use. When collected from near the scalp, hair samples can detect alcohol and drug use for up to roughly 3 months. Hair collection is straightforward, harder to tamper with, and convenient to transport.

A hair sample measuring 1.5 inches and consisting of about 200 strands (comparable to a #2 pencil) nearest the scalp provides 100mg, which is the optimal quantity for both screening and confirmation purposes. For EtG, additional tests, and/or those exceeding 10 panels, a 150mg specimen is advised. It's suggested to weigh the sample using a jeweler's scale. If scalp hair isn't available, equivalent body hair may be taken. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other types (such as facial and axillary hair).

Process Overview

The key stages of processing a drug test result in the laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage where a sample is logged into a lab's system. This involves confirming the sample was properly sealed and delivered, generating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody.

Screening is a preliminary check for substance abuse. Although it's a cost-effective means of ruling out drug use in most samples, a positive result must be confirmed to hold up in court. Presumptively positive samples in Screening need further confirmation.

Should a sample show presumptive positivity during Screening, additional hair from the original sample is used for Extraction. This phase involves removing drugs from hair at a concentration much lower than other testing methods (e.g., urine or oral fluid), rendering hair drug screening a complex method.

Confirmation for any positive screens employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptive positive undergo a wash prior to confirmation if necessary. The entire lab process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for a duration of up to 90 days, unlike urine tests, which have a more restricted detection timeframe.
• Difficulty to cheat: Cheating a hair drug test is challenging, resulting in more reliable outcomes.
• Provides historical data: It offers a pattern of substance use over time rather than just recent usage.

Limitations:

• Cannot detect recent use: Drugs need about 5-7 days to become detectable in hair.
• Cost: Hair drug tests tend to be pricier than other drug testing techniques.
• Variations in results: Factors like hair color and individual differences in hair growth can influence the concentration of drug residues in the hair.

Note: Though often called "hair follicle tests", the test itself evaluates 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.
