Hair Follicle Drug Testing - Feather Sound, FL

What it is, How it works

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and drug use by capturing biomarkers in the hair’s fibers as it grows. When harvested close to the scalp, it can offer a detection window of up to roughly 90 days for alcohol and drugs. Hair is easy to gather, challenging to falsify, and straightforward to transport.

A 1.5-inch segment comprising roughly 200 strands (approximately the thickness of a #2 pencil) from near the scalp can supply 100mg of hair, which is the perfect amount for testing and verification. For EtG, add-ons, and/or examinations exceeding 10 panels, 150mg is advised. It’s advisable to weigh the hair sample with a jeweler's scale. In cases where scalp hair is absent, a similar quantity of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, and others).

Process Overview

The laboratory processing of a hair drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial processing phase of a sample within a lab’s system. This process includes confirming the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not captured through an electronic chain of custody.

Screening is an initial rapid test for drugs of abuse. While Screening is an economical approach to exclude drug usage in most samples, a positive result requires confirmation to be valid for legal purposes. Any samples that test presumptively positive in Screening must undergo secondary confirmation.

Should a sample test presumptively positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which is one reason why hair drug testing is the most complex methodology to conduct.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positive samples are cleansed before confirmation if necessary. The full laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, in contrast to urine tests, which have a shorter detection window.
• Challenging to tamper with: Cheating a hair drug test is difficult, ensuring more reliable outcomes.
• Historical usage pattern: Provides insights into drug use patterns over time, instead of just recent use.

Limitations:

• Cannot detect immediate use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Generally costlier than other drug testing techniques.
• Result variations: Factors like hair color and personal hair growth differences can influence the concentration of drug metabolites in hair.

Note: Commonly called "hair follicle tests", these tests actually analyze the hair strand, not the follicle beneath 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.

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.
