Hair Follicle Drug Testing - Irving, WI

What it is, How it works

Hair analysis has gained recognition as an effective approach for uncovering drug and alcohol consumption. Hair captures long-term indicators of alcohol and drugs by securing biomarkers in the structure of the developing hair shaft. When taken near the scalp, hair can offer a nearly 3-month detection period for alcohol and drugs. Hair collection is straightforward, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment comprising around 200 strands of hair (roughly the width of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal quantity for both screening and confirmation. When testing for EtG, additional analyses, and/or panels exceeding 10, a specimen of 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not available, an equivalent volume of body hair may be gathered. References to head hair are specific to scalp hair alone, while body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The main procedural stages in the lab analysis of a drug test sample encompass four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial handling of a specimen within a lab’s framework. This step ensures the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.

Screening constitutes a preliminary evaluation for substances of abuse. Although Screening offers a cost-efficient method to negate drug use across most samples, positive results require confirmation to be legally accepted. Samples yielding a presumptive positive in Screening must undergo an additional confirmatory test.

In cases of a presumptive positive in the Screening phase, extra hair is extracted from the initial sample for the Extraction stage. During Extraction, drugs are isolated from hair at concentrations notably lower than those in comparable methods (e.g., urine or oral fluid), making hair drug testing the most challenging technique to administer.

Any positive results from Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The complete laboratory evaluation, from Accessioning to Confirmation, undergoes review according to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can observe drug use for up to 90 days, as opposed to urine tests which present a shorter detection timeframe.
• Resistant to tampering: Manipulating a hair drug test is exceedingly difficult, ensuring more reliable outcomes.
• Provides usage trends: It supplies usage patterns over an extended duration, not merely recent use.

Limitations:

• Cannot identify recent consumption: It takes roughly 5-7 days for substances to become discernible in hair.
• Expense: Hair drug testing tends to be pricier than alternative drug testing techniques.
• Result variability: Elements such as hair color and individual diversity in hair growth can impact the levels of drug metabolites present in the hair.

Note: Though frequently termed as "hair follicle tests", the examination focuses on 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.
