Hair Follicle Drug Testing - Lake Villa, IL

What it is, How it works

Hair testing is now regarded as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged history of substance use by capturing biomarkers within the strands. When taken from near the scalp, hair can present an approximate detection period of up to 3 months for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and simple to transport.

A 1.5-inch hair sample containing about 200 strands (akin to the diameter of a #2 pencil) nearest the scalp yields 100mg, which is the optimal amount for analysis. For EtG, add-ons, or tests exceeding 10 panels, 150mg is advised. It's suggested to weigh the sample with a jeweler’s scale. If scalp hair isn’t available, a similar amount of body hair can be used. The term head hair directly refers to scalp hair, while body hair encompasses all other types like facial and axillary hair.

Process Overview

Laboratory handling of a drug test result comprises four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary integration of a sample into a lab’s database. It confirms that the sample is properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and fills out any data not included by an electronic custody chain.

Screening involves a rapid assessment for drug presence. Screening is cost-efficient for excluding drug use in most samples, but a positive result needs validation to be court-admissible. Any presumed positive samples in Screening necessitate another confirmation step.

For samples presumptively positive in Screening, additional hair is taken from the original specimen for Extraction. Drugs are extracted from hair at substantially lesser concentrations than in samples like urine, making hair testing the most challenging methodology.

Any positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed, if necessary, before confirmation. The complete lab process from Accessioning to Confirmation is conducted under both the CAP Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for up to 90 days, whereas urine tests offer a shorter window.
• Hard to manipulate: Cheating a hair drug test is very challenging, leading to more accurate outcomes.
• Shows usage history: It provides a pattern of drug use over time, not just recent use.

Limitations:

• No recent use detection: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug testing generally costs more than other testing methods.
• Result variability: Differences in hair color and growth rates can influence drug metabolite levels in hair.

Note: Though often called "hair follicle tests", the test evaluates the hair shaft, not the follicle beneath the skin.

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.
