Hair Follicle Drug Testing - Weybridge, VT

What it is, How it works

Hair testing has evolved into a valuable resource for identifying drug and alcohol consumption. By trapping biomarkers within the fibers of hair strands as they grow, hair offers a detailed history of substance use. When collected near the scalp, hair samples can detect alcohol and other drugs for as long as three months. The collection is straightforward, tampering is challenging, and shipping is convenient.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (similar in size to a #2 pencil), taken closest to the scalp will yield 100mg of hair, which is the preferred quantity for both screening and confirming results. When testing for EtG, additional substances, or more than 10 panels, a 150mg specimen is advisable. It is suggested to use a jeweler’s scale for weighing. If scalp hair is absent, a similar amount of body hair can be acquired. The term "head hair" pertains exclusively to scalp hair. "Body hair" includes all other types of hair (such as facial or axillary hair).

Process Overview

The laboratory process for drug testing includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial handling of a sample within a lab’s workflow. This involves ensuring the sample is sealed and transported appropriately, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry that isn’t covered by an electronic chain of custody system.

Screening performs a preliminary assessment for substances of abuse. Though cost-effective for dismissing drug use in most cases, a positive screen must be confirmed for legal acceptability. Samples that are presumptively positive during Screening necessitate additional confirmation.

Should a sample test presumptively positive at the Screening stage, additional hair is taken from the original sample for Extraction. During Extraction, drugs are isolated from the hair but at significantly lower concentrations than other methods (like urine or oral fluid), making hair drug testing particularly challenging.

Confirmation of any positive result from screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirming, all presumptively positive samples undergo washing as required. The complete laboratory protocol from Accessioning to Confirmation is scrutinized under the standards of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can reveal drug usage for as long as 90 days, whereas urine tests offer a shorter timeframe.
• Hard to tamper with: Cheating a hair drug test is highly difficult, which enhances accuracy.
• Shows usage patterns: Reflects drug usage behaviors over time, not just recent events.

Limitations:

• Inability to detect recent usage: Detectable drug levels in hair generally appear 5-7 days after use.
• Expense: Typically, hair drug tests are more costly than alternative testing methods.
• Result variability: Factors like hair color and individual growth rates can influence drug metabolite levels in hair.

Note: Commonly termed "hair follicle tests," the analysis actually examines the hair strands, 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.
