Hair Follicle Drug Testing - Sparta, IL

What it is, How it works

Utilizing hair testing is regarded as an effective method for identifying drug and alcohol consumption. The hair can capture a long-term record of drugs and alcohol by embedding biomarkers within the hair strand as it grows. A specimen collected near the scalp offers a detection timeline of up to three months for drugs and alcohol. Hair is easy to gather, challenging to tamper with, and simple to deliver for analysis.

Obtaining a 1.5-inch section consisting of roughly 200 hair strands, similar to the diameter of a #2 pencil, ensures 100mg of hair, an optimal quantity for preliminary and confirmatory testing. For additional testing such as EtG or panels exceeding 10, 150mg of hair is advised. It's best to weigh the specimen using a jeweler's scale. In the absence of scalp hair, a comparable portion of body hair is acceptable. The term head hair used here pertains exclusively to scalp hair. Body hair denotes all other types (facial, axillary, etc.).

Process Overview

The lab procedure for processing drug test outcomes involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of incorporating a sample into the lab system. It entails confirming the proper sealing and shipment of the specimen, assigning it a unique LAN (Laboratory Accessioning Number), and completing any additional data not captured by an electronic chain of custody system.

Screening serves as a preliminary check for substances of abuse. Although Screening is a cost-effective approach to exclude drug use in most samples, any positive result necessitates confirmation to be recognized in a legal setting. Samples indicating presumptive positives in Screening require further confirmation.

In the Screening phase, if a sample is deemed presumptive positive, additional hair from the original specimen is set aside for Extraction. In this process, drugs are extracted from hair at a lower concentration than other tests (e.g., urine or oral fluid), reinforcing hair drug screening as the most complex method to perform.

To confirm a positive Screening outcome, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. All samples that are presumptive positives undergo washing before confirmation as required. The complete lab procedure from Accessioning to Confirmation is overseen under the CAP (College of American Pathologists) Hair categorization and the ISO/IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for as long as 90 days, surpassing the shorter detection period of urine tests.
• Hard to falsify: Cheating a hair drug test is notably difficult, enhancing the accuracy of results.
• Historical overview: It provides insights into drug use over time rather than capturing only recent consumption.

Limitations:

• Cannot identify recent consumption: Drugs become detectable in hair after approximately 5 to 7 days.
• Expense: Generally, hair drug testing incurs a higher cost than alternative drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations.

Note: Commonly known as "hair follicle tests," the analysis is conducted on the hair strand, excluding 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.
