Hair Follicle Drug Testing - Port Vincent, LA

What it is, How it works

Hair testing is increasingly recognized as an effective method to identify alcohol and drug consumption. Hair can offer a prolonged history of substance use by embedding biomarkers within the strands of hair as they grow. Collected near the scalp, hair allows for a detection window of up to roughly three months for alcohol and drugs. Collection is straightforward, tampering is complex, and shipping is convenient.

A hair sample measuring 1.5 inches with approximately 200 strands (akin to a #2 pencil) nearest to the scalp can provide 100mg of hair, considered ideal for both screening and verification. For EtG, add-ons, and/or assessments exceeding ten panels, a 150mg sample is advised. Using a jeweler's scale for measurement is suggested. If scalp hair is not an option, an equivalent amount of body hair can be used. In reference to head hair, it denotes only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

There are four primary stages in the lab procedure for processing drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where a sample is logged into a laboratory's database. This phase ensures that the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finishes any extra data input not included in an electronic chain of custody system.

Screening provides an initial general check for substances of abuse. While Screening is an affordable approach to dismiss drug use in most samples, a positive result needs affirmation to be court-admissible. Any samples flagged as presumptively positive during Screening need follow-up confirmation.

If Screening suggests positivity, more hair is taken from the main specimen for Extraction. In this phase, drugs are extracted from hair at significantly lesser concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging procedure to execute.

Verification of any positive Screening output is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked presumptively positive are cleaned before confirmation when necessary. The entire lab process, spanning from Accessioning to Confirmation, is examined following both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection duration: Hair drug tests can discover drug use up to 90 days, unlike urine tests that have a shorter timeframe.
• Challenging to manipulate: It is highly challenging to manipulate a hair drug test, ensuring more reliable results.
• Gives historical information: It reveals a timeline of drug consumption over an extended period, not just recent use.

Limitations:

• Cannot identify recent use: There is a 5-7 day period before drugs become detectable in hair.
• Cost factor: Hair drug tests usually cost more than other testing approaches.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolites' concentrations in the hair.

Note: While commonly labeled "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Port Vincent, LA, hair follicle testing surpasses urine tests with its superior detection capabilities. Unlike traditional urine testing, hair tests offer an extended window, capturing drug use history months prior. This makes them ideal for employers seeking comprehensive insights. The accuracy and reliability of hair tests ensure a true representation of an individual's substance use.

Extended Detection Window

One of the standout features of hair follicle testing in Port Vincent, LA, is its extended detection window. Hair tests can identify drug use up to 90 days back, offering an in-depth view of an individual's substance history. For employers, this means a clear understanding of an applicant or employee's long-term habits, supporting informed decision-making.

Tamper-Resistant Testing Method

Hair follicle testing in Port Vincent, LA, represents a breakthrough in tampering resistance. Compared to other testing methods, hair samples are far less susceptible to adulteration. Thus, they provide results that are nearly impervious to manipulation—a critical advantage for maintaining the integrity and trustworthiness of drug testing programs.

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.
