Hair Follicle Drug Testing - Mount Sidney, VA

What it is, How it works

Acknowledged as an effective approach to detecting drug and alcohol intake, hair testing provides a comprehensive history of such substances by embedding biomarkers within the hair fibers as they grow. Obtaining samples near the scalp offers a detection window of up to three months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and easily shippable.

To acquire an optimal sample for screening and confirmation, a 1.5-inch piece consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp supplies 100mg of hair. For tests that include EtG, add-ons, or exceed 10 panels, it's advised to utilize 150mg of hair, measurable with a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair is acceptable. "Head hair" refers solely to hair on the scalp, while "body hair" includes all other types (such as facial or axillary hair).

Process Overview

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

At the Accessioning stage, the sample is initially integrated into the lab’s system. This step ensures the sample’s proper sealing and shipping, assigns a Laboratory Accessioning Number (LAN), and completes any additional unexplored data entry that wasn’t captured by an electronic chain of custody system.

The Screening step serves as a preliminary check for drug presence. Although a cost-effective method to exclude drug usage in most samples, any positive screening results require confirmation for legal credibility. Any specimens deemed presumptively positive must undergo secondary verification.

When a sample shows a presumptive positive result in Screening, additional hair from the original collection is extracted for the Extraction phase. Here, drug substances are isolated from hair at notably lower concentrations than other methods (such as urine or oral fluids), accounting for hair drug testing's complexity.

Confirmation for any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all samples with presumptive positive results are washed as necessary. The comprehensive lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair guidelines and complies with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can indicate drug use over a span of up to 90 days, whereas urine testing has a shorter detection timeframe.
• Resistance to deception: Due to the difficulty of cheating, hair drug tests yield more reliable outcomes.
• Tracks usage history: Capable of illustrating a drug usage pattern over time, beyond just recent activity.

Limitations:

• Incapable of identifying recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• More costly: Hair drug testing generally incurs higher costs than other drug testing methods.
• Result variations: Factors like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Despite being frequently termed "hair follicle tests," the analysis concentrates on the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Mount Sidney, VA, the advantages of hair follicle testing over urine testing are clear. Hair tests boast superior detection accuracy and reliability, making them the preferred choice over traditional urine tests. While urine tests are limited to short-term detection, hair tests provide a broader look into an individual's substance history, offering a more dependable and accurate assessment for employers and legal authorities.

Extended Detection Window

A key benefit of hair follicle testing in Mount Sidney, VA, is its extended detection window. Unlike other drug tests, hair follicle tests can detect drug use for up to 90 days. This long detection period provides employers with a more comprehensive view of a candidate's or employee's substance use history, helping make informed decisions based on long-term patterns rather than short-term situations.

Tamper-Resistant Testing Method

In Mount Sidney, VA, hair follicle tests are largely tamper-resistant, significantly reducing the possibility of sample adulteration. This makes them a reliable choice for those who need unquestionable results. The testing process involves collecting hair samples in an observed manner, ensuring that the results are free from manipulation or substitution attempts.

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.
