Hair Follicle Drug Testing - Holliday, TX

What it is, How it works

Considered a robust method, hair testing is deployed for uncovering the use of drugs and alcohol. Hair chronicles a prolonged history of substance use by sequestering biomarkers within its fibers as it grows. When obtained near the scalp, it can reveal consumption patterns of alcohol and other substances over roughly a 90-day span. Collection is straightforward, challenging to tamper with, and facilitates easy shipping.

Taking a 1.5-inch sample, approximately 200 hair strands (similar to the width of a #2 pencil) closest to the scalp provides roughly 100mg of hair, the preferred quantity for both screening and verification. For EtG assessments, add-ons, or tests exceeding 10 panels, it's advised to collect 150mg. Utilizing a jeweler's scale to weigh the sample is advised. If scalp hair isn't available, a similar quantity of body hair can be used. When discussing head hair, it specifically means scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The processing of a drug test outcome in the laboratory includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary incorporation of a sample into a lab's system. This phase encompasses validation of sample sealing and proper shipping, allocation of a random LAN (Laboratory Accessioning Number), and execution of supplementary data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary rapid assessment for illicit drugs. Though cost-effective as a preliminary filter for drug consumption in most samples, a positive screening requires confirmation for legal admissibility. Samples that show presumptive positives during Screening necessitate secondary verification.

Should a specimen show presumptive positivity in the Screening phase, additional hair is drawn from the initial sample for further Extraction preparation. During Extraction, substances are retrieved from the hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), which presents a unique challenge in hair drug testing.

For verification, any positive screening results undergo GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, all presumptive positive samples are cleansed as necessary. From Accessioning to Confirmation, the entire lab procedure is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation benchmarks.

Advantages of hair drug testing:

• Prolonged detection span: Hair drug tests can identify drug usage for a window of up to 90 days, while urine tests offer a brief detection period.
• Difficult to manipulate: Cheating a hair drug test is arduous, enhancing result precision.
• Insightful historical data: Provides a timeline of drug use extending over months, not just recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs may require 5-7 days to manifest in hair samples.
• Expense considerations: Hair drug tests are often pricier than alternative testing techniques.
• Result variability: Elements like hair color and individual hair growth patterns may influence drug metabolite concentration in hair.

Note: The term "hair follicle tests" is a misnomer as the analysis concerns the hair strand itself, not the follicle within 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
