Hair Follicle Drug Testing - Edwardsburg, MI

What it is, How it works

The use of hair analysis has emerged as a significant means for identifying the consumption of drugs and alcohol. The composition of hair captures a comprehensive record of alcohol and drugs by encasing biomarkers within the structure of the developing hair strand. When taken near the scalp, hair can offer an approximate three-month window of detection for alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and convenient for transportation.

A 1.5-inch segment of roughly 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal quantity for analysis and validation. For EtG, additional testing, and/or examinations exceeding 10 panels, 150mg of the sample is advised. It's suggested to use a jeweler’s scale for weighing. Should scalp hair be unavailable, a comparable amount of body hair can be utilized. When discussing head hair, the reference is specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary procedures in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial handling of a sample within a lab's framework. This process involves ensuring the sample was securely sealed and correctly delivered, assigning a random LAN (Laboratory Accessioning Number), and executing any additional data entry not already covered by an electronic chain of custody protocol.

Screening offers an preliminary rapid assessment for drugs of abuse. While Screening serves as a cost-efficient way to exclude drug use in most samples, a positive result must be verified to be legally valid. Samples that test presumptively positive during Screening need further confirmation.

For any samples testing presumptively positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. Here, drug compounds are isolated from hair at lower concentrations than with other techniques (such as urine or oral fluid), making hair drug screenings particularly challenging.

Confirmation of any positive screen involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning through Confirmation is assessed under the CAP (College of American Pathologists) Hair classification and aligned with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug assessments can trace drug consumption for up to 90 days, unlike urine tests that have a limited detection span.
• Resistance to tampering: Hair drug tests are extremely difficult to subvert, enhancing result reliability.
• Chronological usage information: It can illustrate a timeline of drug consumption, not merely recent usage.

Limitations:

• Inability to identify recent consumption: Drugs require roughly 5-7 days to become traceable in hair.
• Expense: Hair drug assessments typically incur higher costs than alternative drug testing approaches.
• Outcome variability: Elements like hair pigment and individual hair growth disparities can influence the level of drug metabolites in the hair.

Note: Although commonly termed "hair follicle tests", the actual analysis occurs on the hair strand, not the follicle underneath 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.
