Hair Follicle Drug Testing - Norris City, IL

What it is, How it works

Hair analysis has emerged as a robust method for identifying substance use. Hair captures a long-term profile of drug and alcohol consumption by trapping markers within the fibers of the hair as it grows. When taken from near the scalp, hair can reveal substance use for a detection window of up to three months. Collecting hair is straightforward, relatively hard to alter, and simple to transport.

A 1.5-inch section consisting of around 200 hair strands (approximately the width of a #2 pencil) nearest the scalp provides 100mg of hair, which is optimal for both screening and validation. For EtG, supplementary tests, and panels exceeding 10, 150mg of hair is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair isn't accessible, an equivalent portion of body hair can be used. When mentioning head hair, it denotes scalp hair specifically. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The primary steps in the lab processing for drug test assessment include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory's protocol. This process verifies proper sealing and shipment of the sample, assigns a Laboratory Accessioning Number (LAN), and completes supplementary data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid evaluation for substance abuse. Although Screening is an economical way to discount drug use in the bulk of samples, a positive outcome necessitates confirmation to be valid in a legal context. Any samples that presumptively test positive in Screening must undergo additional verification.

In cases where a sample tests presumptively positive during Screening, additional hair is obtained from the original sample and prepared for Extraction. Drugs in this phase are extracted from hair at lower concentrations compared to other methods (such as urine or oral fluid), thus making hair drug testing one of the most complex methodologies.

Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed prior to confirmation as required. The entire process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair classification and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection time frame: Hair drug testing can detect drug use for up to 90 days, whereas urine tests have shorter detection periods.
• Difficulty in falsification: Cheating a hair drug test is significantly challenging, thus enhancing result accuracy.
• Chronological substance use data: It offers insights into an individual's drug use pattern over time, beyond recent use.

Limitations:

• Lack of recent use detection: It requires about 5-7 days for drugs to become detectable in hair.
• Higher cost: Hair drug tests are typically more costly than alternative drug testing techniques.
• Variability in outcomes: Elements such as hair color and personal variations in hair growth can influence metabolite concentration in the hair.

Note: While often labeled as "hair follicle tests", the actual analysis focuses on 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.
