Hair Follicle Drug Testing - Tangipahoa, LA

What it is, How it works

Hair examination has increasingly been recognized as a formidable instrument for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers within the strands as they grow. When gathered near the scalp, hair can reveal a detection period of up to roughly three months for drugs and alcohol. Hair is straightforward to gather, challenging to tamper with, and convenient to transport.

A 1.5-inch section consisting of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp will yield 100mg, the optimum sample size for testing and validation. For tests like EtG, supplementary screens, or panels exceeding 10, it is suggested to acquire 150mg of the sample. Utilizing a jeweler’s scale for weighing the sample is advised. Should scalp hair be absent, a similar quantity of body hair can be utilized. References to head hair specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Summary

The lab’s handling of a drug test result comprises four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample’s initial induction into the laboratory framework. It encompasses ensuring the sample's proper sealing and dispatch, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any necessary data entry not present in an electronic chain of custody setup.

Screening involves a preliminary rapid assessment for substance abuse. Though Screening is a cost-efficient approach for dismissing drug usage in most samples, a positive Screening necessitates validation to be court-admissible. Any samples yielding a presumptive positive in Screening must undergo additional confirmation.

Should a sample yield a presumptive positive during the Screening phase, more hair is extracted from the original specimen and readied for Extraction. In Extraction, drugs are retrieved from hair in considerably lower concentrations compared to alternative methods (e.g., urine or oral fluid), underscoring hair drug screening as the most challenging practice to execute.

Confirmation for any positive Screening outcome is executed via GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positive results undergo necessary washing before confirmation. The entire lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Pros of hair drug testing:

• Extended detection period: Hair drug screenings can identify drug use up to 90 days prior, unlike urine tests with a briefer detection timeframe.
• Increased difficulty to falsify: Cheating a hair drug test is exceedingly challenging, thus enhancing result accuracy.
• Insight into usage patterns: It reveals drug use trends over time, beyond just recent consumption.

Drawbacks:

• Inability to detect recent usage: Drugs require approximately 5-7 days to register in hair strands.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variations: Influences like hair color and personal growth differences can impact drug metabolite levels in hair.

Note: Though commonly called "hair follicle tests", the analysis actually involves the hair strand, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
