Hair Follicle Drug Testing - Denton, MT

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair encapsulates a prolonged record of alcohol and drug intake by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair offers a detection timeline of up to three months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the diameter of a #2 pencil) gathered closest to the scalp will yield 100mg of hair, the perfect amount for screening and verification. For EtG, additional tests, and/or panels above 10, 150mg of the sample is suggested. We advise measuring the specimen with a jeweler's scale. If scalp hair isn't an option, a comparable volume of body hair can be gathered. References to head hair pertain solely to scalp hair. Body hair encompasses other hair varieties (such as facial, axillary, etc.).

Process Overview

The primary steps in the lab processing of a drug test outcome involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises initially processing a sample into a lab's system. This process verifies that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not covered by an electronic chain of custody system.

Screening serves as a preliminary rapid check for drug misuse. While cost-effective, a positive Screening result needs Confirmation for legal admissibility. Samples showing presumptive positivity in Screening require further Confirmation.

Should a sample show presumptive positivity during Screening, additional hair is extracted for the Extraction stage. Here, drugs are drawn from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), making hair drug screening particularly challenging.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing prior to Confirmation as required. The complete lab process from Accessioning to Confirmation is reviewed under 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 trace drug use for up to 90 days, unlike urine tests which have shorter detection periods.
• Tough to manipulate: It's notably challenging to deceive a hair drug test, ensuring more dependable results.
• Offers historical insights: It demonstrates a pattern of drug use over time, not merely recent usage.

Limitations:

• Incapable of detecting recent usage: It requires around 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests typically incur higher costs than other testing methods.
• Result variations: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Commonly called "hair follicle tests", the evaluation analyzes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Denton, MT, hair follicle testing surpasses urine tests due to its superior detection accuracy and reliability. Unlike urine tests that typically cover recent drug use, hair tests offer vast detection windows, inclusive from weeks up to 90 days, fostering a thorough understanding of substance history.

Extended Detection Window

Hair follicle drug testing stands out for its extended detection window, identifying substance use up to 90 days in Denton, MT. This prolonged window allows employers to gain a vital overview of an individual’s substance history, crucial for informed decision-making in applicant screening.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
