Hair Follicle Drug Testing - Fort Atkinson, WI

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol usage. Hair captures a historical record of substance use by embedding markers within the strands. When sourced near the scalp, hair offers an approximate 3-month window for detecting alcohol and other substances. The collection process is straightforward, with hair being somewhat resistant to tampering, and it's also easy to transport.

A 1.5-inch segment consisting of about 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for both screening and confirmation purposes. For EtG, add-ons, or tests exceeding 10 panels, it's best to collect 150mg. Using a jeweler’s scale to weigh the specimen is advised. If scalp hair is unavailable, an equivalent amount of body hair can be used. "Head hair" specifically means scalp hair, whereas "body hair" includes all other types (such as facial or axillary hair).

Process Overview

The drug test laboratory process involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory system. This step involves ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and entering any data not captured by an electronic chain of custody system.

Screening provides an initial assessment for drugs of abuse. It is a cost-efficient means to rule out drug use in most samples; however, a positive screen must be confirmed for court admissibility. Samples yielding presumptive positive results in Screening require further confirmation.

With a presumptive positive result in Screening, additional hair is extracted from the original sample for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations than other methods (like urine or oral fluid), explaining the complexity of hair drug screening.

Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as necessary. The entire lab process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can detect drug use up to 90 days, while urine tests offer shorter detection periods.
• Challenging to manipulate: It is highly challenging to falsify a hair drug test, enhancing the accuracy of results.
• Historical insight: It provides insight into drug use patterns over time, not just recent usage.

Limitations:

• Inability to spot recent usage: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug tests usually incur higher costs compared to other methods.
• Result variability: Hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests," the analysis actually evaluates 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. 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.
