Hair Follicle Drug Testing - Wales, MN

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. The hair gives an extensive timeline of substance use by preserving biomarkers within the fiber of the emerging hair. When taken from near the scalp, hair can yield approximately a 3-month detection period for substances. Hair collection is straightforward, relatively tamper-resistant, and convenient for transport.

A 1.5-inch section of around 200 hairs, comparable to a #2 pencil's size, adjacent to the scalp provides 100mg of hair, the optimal quantity for both screening and verification. For EtG, additions, and/or examinations exceeding 10 panels, a sample of 150mg is advised. We suggest measuring the hair sample using a jeweler’s scale. In the absence of head hair, a similar quantity of body hair can be used. Head hair denotes hair strictly from the scalp. In contrast, body hair signifies other types (facial, axillary, etc.).

Process Overview

There are four primary stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory's system, which includes checking the integrity and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any pending data entry not captured by an electronic chain of custody.

Screening is a preliminary assessment for drugs. While cost-effective for dismissing drug use in most samples, a positive screen must be corroborated for legal acceptability. Positive results in Screening necessitate a secondary confirmation procedure.

For samples presumptively positive at Screening, additional hair is taken from the sample for Extraction. In this process, drug elements are separated from hair at lower concentrations than alternative methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive specimens undergo cleansing before confirmation as required. The complete lab process from Accessioning through Confirmation is reviewed according to CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments identify drug use over a 90-day span, as opposed to the shorter detection period of urine tests.
• Hard to manipulate: Cheating a hair drug test is difficult, enhancing the reliability of results.
• Reveal usage patterns: It offers a timeline of drug use, not limited to recent instances.

Limitations:

• Incapacity to detect recent use: Drugs only become traceable in hair after approximately 5-7 days.
• Expense: Hair drug testing is often pricier than other testing modalities.
• Result variability: Factors like hair color and individual hair growth rates can alter drug metabolite concentration in hair.

Note: Although commonly termed "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Wales, MN, hair follicle testing surpasses traditional urine tests in several ways. While urine tests are limited to detecting recent drug use, hair testing offers a superior detection accuracy that reaches up to 90 days. This longer detection window provides a more comprehensive view of an individual's drug use history.

Extended Detection Window

In Wales, MN, hair follicle testing is prized for its extended detection window, detecting substances consumed up to 90 days prior. This capability grants employers invaluable insight into an individual's long-term drug use, surpassing the limitations of urine testing, which is constrained to a much shorter look-back period.

Tamper-Resistant Testing Method

Hair follicle tests in Wales, MN, greatly diminish the chances of sample tampering, presenting a reliable option for authentic results. The difficulty of adulterating a hair sample, as opposed to a urine sample, elevates the trustworthiness of hair testing, ensuring its results remain unquestioned and valid for crucial decision-making.

Convenient Nationwide Locations

With convenient testing locations throughout Wales, MN, and nationwide, hair follicle drug testing is accessible and easy. Our network allows for quick, hassle-free access to testing services, ensuring that you can find a nearby center wherever you are, without the stress of lengthy travel or appointments.

Simple, Confidential Process

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.
