Hair Follicle Drug Testing - Danville, AR

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and other drugs by capturing biomarkers within the fibers of the developing hair strand. When gathered close to the scalp, hair can offer a detection period of up to approximately 3 months for alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and easily transportable.

A 1.5-inch segment of around 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp will yield 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the specimen is preferred. We suggest using a jeweler’s scale to measure the sample. If scalp hair isn't available, an equivalent quantity of body hair may be gathered. When we mention head hair, we specifically mean scalp hair. Body hair covers all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into a laboratory’s system. This process verifies that the sample was suitably sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.

Screening is an initial rapid evaluation for drugs of abuse. Screening serves as a cost-efficient method to negate drug usage in the majority of samples; however, a positive screen necessitates confirmation to be legally credible. Samples that are preliminarily positive in Screening need secondary confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the original specimen for Extraction preparation. Here, drugs are extracted from hair at notably lower concentrations than other methods (such as urine or oral fluid), making hair drug screening a particularly challenging methodology to execute.

Confirmation of any positive screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo necessary washes before confirmation. The complete laboratory process, from Accessioning to Confirmation, is evaluated against both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Hard to manipulate: Cheating on hair drug tests is highly challenging, enhancing result accuracy.
• Historical insight: It offers a timeline of drug use over an extended duration, not merely recent usage.

Limitations:

• Inability to detect recent use: Drugs are only detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically costlier than other drug testing methods.
• Result variability: Differences such as hair color and personal variations in hair growth can influence drug metabolite concentrations in the hair.

Note: Despite often being termed "hair follicle tests", the analysis is performed on the hair strand and not the sub-surface hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine tests in Danville, AR? The benefits are clear. Hair tests provide superior detection accuracy because they screen for substances over a longer period than urine tests, which mainly capture recent usage. This makes it an invaluable tool for employers looking to maintain a drug-free environment, as they can rely on the reliability and precision such tests offer.

Extended Detection Window

Hair follicle testing in Danville, AR, boasts an extended detection window, analyzing drug use for up to 90 days. This method provides employers with a detailed view of an individual’s substance use history, offering a more comprehensive assessment than shorter-term urine tests. This benefit assures employers of a thorough evaluation of their employees' long-term habits.

Tamper-Resistant Testing Method

Hair follicle testing is the preferred choice in Danville, AR, for its tamper-resistant properties. Unlike urine tests, hair testing reduces the risk of sample adulteration, ensuring reliable and trustworthy results. This quality gives stakeholders confidence in the validity of the outcomes, reinforcing the test’s integrity and dependability in various settings.

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.
