Hair Follicle Drug Testing - Alto, WI

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair captures a timeline of drug use by embedding biomarkers within the fibers of the growing hair shaft. Collected near the scalp, hair can reflect drug and alcohol usage over a timeframe of up to roughly three months. Its collection is straightforward, it is moderately resistant to tampering, and it can be easily mailed.

Gathering a 1.5-inch segment of approximately 200 strands (equivalent to the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal volume for both initial screening and subsequent confirmation. For EtG assessments, additional tests, or those exceeding 10 panels, a sample of 150mg is advisable. Use a jeweler’s scale for weighing the sample. When scalp hair isn't available, an equal volume of body hair is acceptable. "Head hair" pertains strictly to scalp hair, whereas "body hair" encompasses all other varieties (like facial, axillary, etc.).

Procedure Summary

The four essential stages in lab processing of a drug testing sample include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to integrating a sample into the lab’s system initially. This stage ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any additional information input absent in an electronic chain of custody process.

Screening entails a preliminary overview for substance abuse. While Screening is an economical method to eliminate drug use in most samples, legal proceedings demand verification of a positive screen. Samples that test presumptively positive during Screening necessitate further confirmation.

Should a sample present a presumptive positive result during Screening, additional hair from the specimen is utilized for Extraction. Here, drugs are isolated from hair at notably lower concentrations compared to other methods (e.g., urine or saliva), rendering hair drug testing the most complex to execute.

Confirming any positive screen result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptively positive samples undergo washing as needed. The entire lab procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and certified against ISO / IEC 17025 standards.

Benefits of Hair Testing:

• Extended detection period: Hair tests reveal drug use over a span of up to 90 days, unlike urine tests with briefer detection times.
• Hard to manipulate: It's incredibly challenging to falsify a hair drug test, ensuring higher accuracy of results.
• Tracks historical usage: It can show a timeline of drug consumption across several months, not just recent activity.

Drawbacks:

• Cannot identify recent use: Drugs take around 5-7 days post-usage to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than alternative testing approaches.
• Inconsistent results: Variables like hair color and individual hair growth rates can impact metabolite levels in the hair.

Note: Although often termed "hair follicle tests," the analysis focuses on the hair strand, 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.
