Hair Follicle Drug Testing - Snellville, GA

What it is, How it works

Hair testing is seen as a robust method for identifying drug and alcohol consumption. Hair records a persistent history of alcohol and drugs by embedding biomarkers within the strands of the hair as it grows. Obtained near the scalp, hair can reveal a detection window of up to around three months for alcohol and other substances. It's easy to gather, harder to tamper with, and convenient to transport.

A 1.5-inch sample, about 200 hair strands (comparable to the volume of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the perfect sample size for both screening and verification. For EtG additions and/or tests exceeding 10 panels, 150mg of the sample is advisable. Utilize a jeweler’s scale to weigh the sample. If scalp hair isn't available, collect an equivalent amount of body hair. References to head hair pertain exclusively to scalp hair. Conversely, body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The key phases in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary processing of a sample into a laboratory’s system. This stage ensures the sample was securely sealed and sent, assigns a LAN (Laboratory Accessioning Number) randomly, and completes outstanding data entry not managed by an electronic chain of custody system.

Screening is a preliminary check for drug abuse. Although Screening is an economical approach to rule out drug usage for most samples, a positive finding needs validation to be accepted in a legal context. Any samples flagged as presumptively positive need additional confirmation.

If a sample is marked as presumptively positive at the Screening phase, further hair is taken from the primary sample for Extraction. During Extraction, drugs are retrieved from hair at a significantly lower level than in other techniques (e.g., urine or oral fluid), presenting challenges in hair drug screening execution.

Validation of any screened positive result is executed through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive undergo a cleansing process before confirmation as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accredited standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug use for up to 90 days, as opposed to urine tests which offer a limited detection timeframe.
• Challenging to manipulate: Cheating on a hair drug test is notably hard, ensuring heightened accuracy.
• Historical insight: It can reveal a pattern of drug occurrence over time, instead of merely recent usage.

Limitations:

• Incapable of identifying recent usage: Drugs become detectable in hair in approximately 5-7 days.
• Expense: Hair drug tests are typically more costly than alternative drug testing techniques.
• Result variability: Elements like hair color and individual hair growth patterns may alter drug metabolite concentrations in hair.

Note: While often labeled as "hair follicle tests", it is the hair strand, not the beneath-the-scalp hair follicle, that undergoes analysis.

Why Hair Follicle Testing Beats Urine Testing

When comparing drug testing methods in Snellville, GA, hair follicle tests take the lead. Unlike urine testing, hair tests deliver superior accuracy in substance detection. While urine tests require more frequent administration due to shorter detection windows, hair follicle tests analyze a broader history, offering reliable results that are hard to dispute.

Extended Detection Window

Boasting an extended detection window, hair follicle testing in Snellville, GA, gives employers a thorough overview of an individual's substance history. With the ability to reveal drug use up to 90 days prior, this test offers a wider scope of past behavior than traditional methods, thereby enhancing the screening process for better hiring decisions.

Tamper-Resistant Testing Method

In Snellville, GA, hair follicle testing stands as a robust method against tampering. The test significantly lowers the chances of sample adulteration, providing results that are trustworthy and difficult to manipulate. This ensures that any substance use detected is accurate and reflective of the subject's true state.

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.
