Hair Follicle Drug Testing - Lorenzo, NE

What it is, How it works

Hair analysis is recognized as a robust method for detecting both drug and alcohol consumption. Hair retains markers of alcohol and drugs over time, capturing them in the strands’ fibers as they grow. A collection near the scalp can present up to a 3-month timeframe for detecting alcohol and other substances. The collection process is uncomplicated, tampering is challenging, and shipping is straightforward.

A sample size of 1.5 inches, comprising around 200 hairs (approximately the width of a #2 pencil) nearest to the scalp, yields 100mg—the optimal amount for both screening and validation. For EtG tests, additional checks, and/or tests exceeding 10 panels, 150mg is advisable. We suggest measuring the sample with a jeweler’s scale. If head hair is unavailable, a comparable quantity of body hair may be used. Head hair specifically refers to scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a lab’s framework. This step verifies proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and addresses any supplementary data entry omitted by an electronic chain of custody.

Screening is a preliminary analysis for detecting drugs of abuse. Although cost-efficient for negating drug presence in most samples, positive screenings necessitate confirmation to be admissible in legal proceedings. All samples testing positive in Screening require further validation.

If a sample tests positive during Screening, additional hair is extracted from the initial specimen for further analysis in Extraction. This phase isolates drugs from hair at concentrations significantly lower than other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug screening.

Validated positive screenings undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples testing presumptively positive are cleansed prior to confirmation as deemed necessary. The entire procedural cycle from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and in compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair tests can reveal drug use for up to 90 days, unlike urine tests with shorter detection durations.
• Cheating is challenging: Its design makes it tough to manipulate, ensuring more reliable results.
• Historical insight: These tests present a timeline of drug usage, offering more than merely recent use.

Limitations:

• Incapable of spotting recent use: Drugs become detectable in hair usually after 5-7 days.
• Expense: Hair tests typically incur higher costs compared to alternative testing approaches.
• Inconsistencies: Hair color and personal hair growth differences can impact drug metabolite levels.

Note: While commonly termed "hair follicle tests," the analysis actually focuses on the hair strand, not the hair root 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. 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.
