Hair Follicle Drug Testing - Minnetrista, MN

What it is, How it works

Hair analysis has gained recognition as an effective method for uncovering drug and alcohol consumption. The hair retains a historical record of alcohol and drug use by embedding biomarkers within the fibers of the hair as it grows. When sourced from near the scalp, the detection period for alcohol and drugs can extend up to about three months. Collection is straightforward, tampering is relatively challenging, and shipping is hassle-free.

A hair sample weighing 100mg, typically 1.5 inches long and consisting of around 200 strands (similar in thickness to a #2 pencil), is optimal for testing and validation. For EtG, additional tests, and when examining over 10 drug panels, a 150mg specimen is advised. Utilizing a jeweler’s scale for weighing samples is recommended. Should there be no head hair, a similar quantity of body hair can be utilized. "Head hair" refers specifically to hair from the scalp, whereas "body hair" encompasses other types such as facial and axillary hair.

Process Overview

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

Accessioning entails the preliminary integration of a sample into a lab’s database. It involves confirming the sample's secure sealing and transport, assigning a random Laboratory Accessioning Number (LAN), and finalizing data entry omitted by an electronic chain of custody system.

Screening provides an initial assessment for substances of misuse. Although it offers a budget-friendly approach to dismiss drug use in most cases, any positive findings must be verified to hold up in legal proceedings. Samples flagged as presumptively positive need follow-up confirmation.

Upon identifying presumptive positivity in Screening, more hair is extracted from the original sample for the Extraction phase. At this juncture, drug compounds are isolated from hair at notably reduced concentrations compared to other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation of any screening positives is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug consumption up to 90 days, whereas urine tests cover a smaller time frame.
• Hard to deceive: Cheating a hair drug test is quite challenging, ensuring higher accuracy of results.
• Offers historical insight: It reveals patterns of drug use over time, not merely recent activity.

Limitations:

• Inability to detect recent use: A span of around 5-7 days is required for drugs to show in hair.
• Expense: Hair tests usually cost more compared to other drug testing approaches.
• Result variability: Elements such as hair color and individual growth rates can alter drug metabolite amounts in hair.

Note: Although commonly called "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The advantages of hair follicle testing in Minnetrista, MN, over traditional urine tests are significant. Hair testing showcases superior detection capabilities, offering a more comprehensive and accurate insight into an individual's substance use history.

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.
