Hair Follicle Drug Testing - Sharon, VT

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 timeline of substance use by ensnaring biomarkers within its growing fibers. When obtained near the scalp, hair can reveal substance use over a period of up to three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A sample size of 1.5 inches from around 200 hair strands (comparable to a #2 pencil's width) near the scalp yields 100mg, an ideal amount for initial analysis and verification. For EtG, additional tests, and panels exceeding 10, a 150mg sample is advised. It's suggested to measure the sample on a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be used. "Head hair" implies scalp hair exclusively, while "body hair" encompasses other types, such as facial and axillary.

Process Overview

The laboratory handling of a drug test result consists of four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the sample's preliminary integration into the lab system. This step verifies correct sealing and shipment of the sample, allocates a unique LAN (Laboratory Accessioning Number), and completes data entry not covered by an electronic custody system.

Screening involves a preliminary check for substances. Though cost-effective for excluding drug use in most samples, positive screenings must be confirmed for legal acceptability. Samples showing potential positive results require further verification.

Should a sample show a presumptive positive at Screening, more hair from the initial collection is readied for Extraction. Here, substances are isolated from the hair at significantly lower concentrations compared to urine or oral fluid methods, highlighting the complexity of hair drug screening methodology.

Results deemed positive during Screening are corroborated through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are washed beforehand as necessary. Every stage from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair standard and accreditation per ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair tests can ascertain drug use up to 90 days prior, unlike urine tests that have a more limited timeframe.
• Increased challenge to compromise: Results from hair drug tests are more reliable due to the difficulty in manipulation.
• Patterns over time: The testing reveals ongoing drug use over time, not solely recent consumption.

Limitations:

• Cannot identify immediate use: Drugs become detectable in hair after roughly 5-7 days.
• Expense: Hair drug tests often incur higher costs than other testing techniques.
• Result variability: Variables such as hair color and individual growth rates might influence drug metabolite levels in hair.

Note: Although sometimes called "hair follicle tests", the examination targets 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.
