Hair Follicle Drug Testing - Bowmore, NC

What it is, How it works

Hair testing is recognized as a highly effective method for detecting drug and alcohol consumption. It enables the identification of substance use over an extended period by preserving biomarkers within the fibers of the growing hair strand. When collected nearer to the scalp, hair can offer a detection window of up to approximately 3 months for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and convenient for transport.

A 1.5-inch sample containing around 200 hair strands (roughly the diameter of a #2 pencil) cut close to the scalp yields 100mg of hair, which is the optimal sample quantity for both screening and confirmation. For EtG, supplementary tests, or panels exceeding 10 tests, 150mg of the specimen is advised. It's recommended to measure the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be collected. When mentioning head hair, it refers specifically to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results primarily involves Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial incorporation of a sample into a lab's system. This step includes ensuring that the sample was correctly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and carrying out any additional data entry not provided by an electronic chain of custody system.

Screening consists of a preliminary quick assessment for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug use in most samples, a positive screen must be verified to be admissible in legal proceedings. Samples deemed presumptively positive during Screening require further confirmation.

If a sample tests presumptively positive during the Screening stage, an additional portion of hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), hence hair drug screening is the most complex methodology to execute.

Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples presumed positive undergo washing before confirmation if necessary. The entire laboratory procedure 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 drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection timeframe.
• High reliability: It is exceptionally challenging to manipulate a hair drug test, ensuring more precise results.
• Insightful historical data: It can reveal a pattern of drug consumption over time, rather than just recent use.

Limitations:

• Inability to detect recent use: It takes roughly 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are typically more costly compared to alternative drug testing methods.
• Result variability: Factors including hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: While frequently referred to as "hair follicle tests", the analysis is performed on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In contrast to traditional urine tests, hair follicle testing in Bowmore, NC, proves superior in two key areas: detection accuracy and reliability. Where urine tests might miss evidence of long-term substance use, hair testing brings a comprehensive approach, offering robust data that stands up to scrutiny. This method ensures a clear and thorough assessment, diminishing doubts about recent behavior.

Extended Detection Window

One of the most remarkable advantages of hair follicle testing in Bowmore, NC, is its extended detection window. It captures a much broader history of drug use, often up to 90 days, providing employers a comprehensive understanding of an individual's substance habits. This capability is unmatched, offering insights well beyond the limitations of urine tests.

Tamper-Resistant Testing Method

The hair follicle drug testing method significantly increases reliability due to its resilience against tampering. In Bowmore, NC, these tests lower the chance of sample adulteration. The structure and rigor of the process ensure undeniable and trustworthy results, reinforcing the integrity of findings for both employer and employee security.

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.
