Hair Follicle Drug Testing - Breda, IA

What it is, How it works

Hair testing is increasingly viewed as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by embedding biomarkers in the fiber structure of the growing strand. When taken near the root, the hair can offer up to a 3-month detection period for substances. Hair is easy to gather, hard to alter, and simple to transport.

A 1.5-inch segment of approximately 200 hairs (similar in size to a #2 pencil) closest to the scalp will yield 100mg, which is an optimal sample size for both screening and validation. For EtG, additional tests, or panels exceeding 10, 150mg of hair is advisable. Measuring the sample with a jeweler's scale is suggested. If scalp hair isn't accessible, a comparable amount of body hair can be used. When mentioning head hair, we refer solely to scalp hair. Other hair types (e.g., facial, axillary) are classified as body hair.

Process Overview

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

Accessioning entails the preliminary processing of a specimen into a lab's system. This involves confirming that the specimen was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent from an electronic custody record.

Screening performs an initial rapid assessment for drugs of abuse. Although Screening is an economical technique to exclude drug usage on most samples, a positive outcome needs confirmation for court admissibility. Samples with presumptive positive results in Screening necessitate a subsequent confirmation step.

If a sample tests presumptively positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. During Extraction, substances are isolated from hair at concentrations significantly lower than in other testing methods (such as urine or saliva), making hair drug screening the most challenging method to execute.

Confirmation of any positive Screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any samples with presumptively positive results undergo washing prior to confirmation if needed. The entire lab procedure from Accessioning to Confirmation is audited in accordance with the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use for up to three months, unlike urine tests which have a shorter timeframe.
• Resistant to tampering: Cheating a hair drug test is extremely challenging, ensuring more reliable outcomes.
• Tracks usage history: It can illustrate a pattern of drug use over time, beyond recent consumption.

Limitations:

• Fails to detect recent use: Drugs take about 5-7 days to become traceable in hair strands.
• Expense: Hair drug tests tend to be costlier than alternative testing methods.
• Result variability: Aspects like hair color and individual hair growth rates can influence metabolite concentration in hair.

Note: Although often called "hair follicle tests," the analysis targets the hair shaft and 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.
