Hair Follicle Drug Testing - Lottaville, IN

What it is, How it works

Seen as a powerful means for identifying drug and alcohol consumption, hair testing offers a detailed long-term record by embedding biomarkers within the fibers of the growing hair. When collected near the scalp, it can offer a detection span of up to roughly three months for detecting drugs and alcohol. Hair samples are easy to gather, hard to tamper with, and uncomplicated to send off.

A sample measuring 1.5 inches with approximately 200 hair strands (roughly the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the preferred amount for thorough testing and verification. For tests like EtG, additional components, and/or evaluations exceeding 10 panels, 150mg of hair is advisable. Using a jeweler's scale for weighing the sample is suggested. If head hair isn't accessible, a similar quantity of body hair can be collected. Note that head hair refers strictly to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).

Process Overview

Processing a drug test in the lab involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about initially processing a sample into a laboratory setup. This step involves confirming that the sample was sealed and delivered properly, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry not covered by an electronic chain of custody system.

Screening involves a preliminary quick assessment for drugs of abuse. While this step is an economical way to exclude drug use in the majority of specimens, a positive screening must be confirmed for court admissibility. Samples presumed positive in Screening necessitate secondary verification.

If a sample is suggestively positive during Screening, additional hair is extracted from the initial sample and readied for Extraction. At this phase, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), underscoring why hair drug testing is the most challenging technique to conduct.

Confirming any positive screening finds relies on GC/MS, GC/MS/MS, or LC/MS/MS methods. Any samples that tested presumptive positive are cleansed before confirmation if needed. The comprehensive laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and meets the accreditation for ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can unveil drug use for up to 90 days, surpassing the shorter detection period of urine tests.
• Challenging to evade: Hair drug tests are notably hard to cheat, resulting in more reliable results.
• Reveals past usage: By providing a record of drug use over time, it goes beyond recent usage detection.

Limitations:

• No detection of recent usage: Drugs take about 5-7 days to become discernible in hair.
• Expense: Hair drug tests typically cost more than other drug testing alternatives.
• Result variability: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: The term "hair follicle tests" is often a misnomer, as the analysis focuses on the hair shaft and not the follicle beneath the skin

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.
