Hair Follicle Drug Testing - Falling Spring, VA

What it is, How it works

Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands of growing hair, offering a long-term history of substance use. When gathered near the scalp, hair can reveal a detection period of up to roughly 3 months for drugs and alcohol. Hair collection is straightforward, somewhat resistant to tampering, and simple to send.

A 1.5-inch sample containing approximately 200 hair strands (similar to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for screening and verification. For EtG, supplementary tests, and tests exceeding 10 panels, a specimen measuring 150mg is advised. It's suggested to measure the specimen on a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be collected. References to head hair exclusively denote scalp hair. Body hair includes all other hair varieties (facial, axillary, etc.).

Process Overview

The major laboratory processing phases in determining a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary task of inputting a sample into a laboratory’s system. This step involves checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and also completing additional data input that isn't included by an electronic chain of custody system.

Screening is a preliminary rapid examination for drugs of abuse. Although Screening is an economical way to negate drug usage in most samples, a positive screen requires confirmation for court use. Any samples that show a presumptive positive result in Screening necessitate a secondary confirmation.

Should a sample indicate a presumptive positive result in the Screening phase, more hair is retrieved from the initial sample and is readied for Extraction. In Extraction, the concentration of drugs extracted from hair is much lower than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging methodology to execute.

The Confirmation of any positive screening result is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples are washed before the confirmation process as required. The entire laboratory process, from Accessioning to Confirmation, undergoes review 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 timeframe: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have a more limited detection span.
• Resistance to manipulation: It is extremely challenging to manipulate a hair drug test, ensuring more accurate outcomes.
• Offers historical insight: It provides a pattern of drug usage over time, rather than only recent use.

Limitations:

• Inability to detect recent use: Drugs take around 5-7 days to be detectable in hair.
• Expense: Hair drug testing is generally pricier than other drug testing procedures.
• Result variations: Elements like hair color and personal hair growth rates can impact drug metabolite concentrations in hair.

Note: Commonly known as "hair follicle tests," the test itself examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing offers distinct benefits over urine tests in Falling Spring, VA. Superior detection accuracy is a primary advantage, with hair tests providing reliable results over a longer period. Unlike urine tests, hair samples are difficult to adulterate, reducing the risk of tampering. This makes hair follicle testing the method of choice for employers and legal settings that require precise and reliable drug screening.

Extended Detection Window

In Falling Spring, VA, the extended detection window offered by hair follicle testing provides significant advantages. This method traces drug use up to 90 days back, offering employers a comprehensive insight into an employee's substance use history. Such a long-term view is invaluable for gauging consistent drug use, which urine tests, limited to shorter detection spans, cannot provide.

Tamper-Resistant Testing Method

Hair follicle tests in Falling Spring, VA, offer a tamper-resistant solution to drug screening. The method's design makes it nearly impossible to cheat, as altering hair samples is significantly harder than altering urine samples. This ensures more dependable results, giving employers and courts confidence in the validity of the test outcomes.

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.
