Hair Follicle Drug Testing - Virden, IL

What it is, How it works

Hair assessments are regarded as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by embedding biomarkers within its fibers as it grows. When taken from near the scalp, hair can reflect a detection period of up to approximately 90 days for alcohol and other drugs. The collection process for hair is straightforward, it is a bit challenging to tamper with, and it is simple to mail.

A sample of 1.5 inches, roughly 200 hair strands (analogous to the thickness of a #2 pencil) close to the scalp, provides 100mg of hair, which is the ideal quantity for verification and analysis. For EtG, additional testing, and/or analyses exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is not an option, collecting an equivalent quantity of body hair is permissible. Head hair denotes scalp hair exclusively, whereas body hair encompasses other types such as facial, axillary, etc.

Process Overview

The four principal stages in the laboratory handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab’s system. This step ensures the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from an electronic chain of custody system.

Screening involves a preliminary rapid evaluation for drugs of abuse. Although Screening offers a cost-efficient method to dismiss drug usage for most samples, a confirmed positive screen is critical for courtroom admissibility. Specimens presumed positive in Screening require an additional verification.

Should a sample appear presumptively positive during Screening, more hair from the original sample is used in Extraction. Here, drugs are extracted from hair at a considerably lower concentration than in other methods (like urine or saliva), making hair drug testing the most demanding methodology to execute.

Any positive screening outcomes are confirmed through GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed positive undergo washing as necessary before confirmation. The complete lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation conforming to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests offer a detection capability of drug use spanning up to 90 days, unlike urine tests which have a shorter detection duration.
• Difficulty to cheat: Cheating on a hair drug test is remarkably difficult, enhancing the result reliability.
• Provides historical data: It presents a pattern of substance use over a period, rather than just recent activity.

Limitations:

• Cannot detect recent use: Drugs become traceable in hair only after about 5-7 days post-consumption.
• Cost: Generally, hair drug tests incur higher costs compared to other drug testing techniques.
• Variations in results: Elements such as hair pigmentation and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the test fundamentally evaluates the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing stands superior to traditional urine testing in Virden, IL. While both methods aim to detect drug use, hair testing offers far greater detection accuracy. Unlike urine tests, hair tests capture a wider timeframe of substance use, thus providing an extensive history rather than a short snapshot, and reducing the potential for false negatives.

Extended Detection Window

Hair follicle testing extends the boundaries of drug detection in Virden, IL, by covering up to 90 days of substance history. This comprehensive window allows employers to gain thorough insights into the past behavior of applicants or employees. Unlike other limited testing methods, hair follicle tests provide a broader scope of detection, ensuring more informed decisions.

Tamper-Resistant Testing Method

The integrity of hair follicle testing in Virden, IL, is unmatched, as it significantly minimizes the risk of sample tampering. This reliable method ensures the detection results are trustworthy and remain unquestionable, providing confidence in the accuracy of the findings and reducing the potential for testing manipulation.

Convenient Nationwide Locations

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.
