Hair Follicle Drug Testing - Rock Falls, IL

What it is, How it works

Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair offers an extended history of alcohol and drug use by capturing biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can provide a detection period of up to about three months for alcohol and other substances. Hair is easy to collect, relatively difficult to tamper with, and simple to transport.

A 1.5-inch hair sample of approximately 200 strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for screening and confirmation. For those testing for EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advised. It's advisable to measure the specimen using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a specimen into a lab’s system. This step ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.

Screening performs an initial rapid check for drugs of abuse. While Screening offers a cost-effective method to exclude drug use in most samples, a positive screen must be confirmed for court admissibility. Samples that are presumptively positive during Screening undergo a secondary confirmation.

If a sample tests positive in the Screening stage, additional hair is extracted from the initial specimen and prepared for Extraction. Here, drugs are isolated from hair at a notably lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All suspect positive samples undergo washing as required prior to confirmation. The complete laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests detect drug use for up to 90 days, in contrast to the shorter detection period in urine tests.
• Difficulty to cheat: A hair drug test is very hard to falsify, which enhances result accuracy.
• Provides historical data: It can present a usage pattern over a duration, rather than just recent use.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for drugs to show up in hair.
• Cost: Hair drug tests tend to be more costly than other testing methods.
• Variations in results: Elements like hair color and personal hair growth variations can influence drug metabolite concentration in the hair.

Note: Although often called "hair follicle tests", the test examines the hair strand and not the hair 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.
