Hair Follicle Drug Testing - Odell, TX

What it is, How it works

Hair analysis is increasingly recognized as a potent method for identifying substance use. By embedding biomarkers within the fibers of a developing hair strand, hair offers a prolonged history of alcohol and drug usage. When sampled near the scalp, hair can reveal a detection period for up to around three months for substances. Hair collection is straightforward, hard to tamper with, and easily transported.

A sample measuring 1.5 inches comprised of roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp yields 100mg, which is the optimal quantity for both screening and verification. For EtG, additional tests, and/or beyond 10-panel tests, a specimen of 150mg is advisable. It's recommended to weigh the specimen using a jeweler's scale. If scalp hair can't be obtained, a comparable quantity of body hair can be used. When noting head hair, we're specifically referring to scalp hair only. Body hair encompasses any other types (such as facial, axillary, etc.).

Process Overview

The lab processing of a drug test result involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial assimilation of a specimen into a lab's system. This step ensures the specimen was securely sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and manages any further data input not supplied by an electronic custody chain system.

Screening offers an initial rapid evaluation for substance use. Although Screening is an economical means to eliminate drug consumption in most samples, a positive result must be verified for legal admissibility. Any samples that are preliminarily positive in Screening must undergo further confirmation.

In cases where a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample for the Extraction phase. During Extraction, substances are removed from hair at notably lower concentrations compared to other methods (such as urine or oral fluids), which makes hair drug analysis the most challenging process.

Any positive screening outcomes are validated using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity undergo washing before confirmation if required. Each laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine tests with a shorter detection timeframe.
• Resilience to tampering: Attempting to cheat a hair drug test proves much more arduous, enhancing result reliability.
• Historical consumption data: It reveals a trend of substance usage over an extended period, not solely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs require approximately 5-7 days to manifest in hair samples.
• Expense: Hair drug evaluations generally incur higher costs than alternative testing approaches.
• Result variability: Aspects like hair pigmentation and personal hair growth disparities can influence metabolite concentrations in hair samples.

Note: Despite being referred to as "hair follicle tests," the examination itself evaluates the hair strand, not the follicle beneath the scalp.

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.
