Hair Follicle Drug Testing - Peru, IL

What it is, How it works

Hair testing emerges as a robust tool for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by embedding biomarkers within the growing hair fibers. When collected close to the scalp, hair can offer an approximately three-month detection window for drugs and alcohol. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A hair sample measuring 1.5 inches of about 200 strands (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, which is ideal for screening and confirmation. For tests including EtG, add-ons, and/or those exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be utilized. References to head hair denote scalp hair exclusively, whereas body hair encompasses other types of hair (facial, axillary, etc.).

Process Overview

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

Accessioning includes the initial integration of a sample into a laboratory’s system. This process checks the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not handled by an electronic chain of custody system.

Screening is a preliminary examination for substances of abuse. Although Screening is a cost-effective method to exclude drug use in most samples, a positive screen must be confirmed for legal admissibility. Samples presumed positive during Screening necessitate further confirmation.

Should a sample test positive presumptively in the Screening phase, additional hair from the original specimen is prepared for Extraction. During this phase, drugs are extracted from hair at concentrations lower than other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation, as needed. The entire process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests detect drug use for up to 90 days, a duration longer than urine tests.
• Challenge to circumvent: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Provides usage history: It reveals drug use patterns over time, beyond immediate use.

Limitations:

• Cannot gauge recent use: A 5-7 day period is needed before drugs become traceable in hair.
• Expense: Hair drug tests are usually more costly compared to other methods.
• Result variability: Aspects like hair color and individual hair growth rates can influence drug metabolite concentrations.

Note: While commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
