Hair Follicle Drug Testing - Istachatta, FL

What it is, How it works

Hair testing is recognized as a potent method for detecting drug and alcohol consumption. Hair offers an extended historical record of these substances by embedding biomarkers in the strands’ fibers as they grow. When taken near the scalp, it grants a detection range for alcohol and other drugs of approximately 3 months. Hair is easy to gather, not easily tampered with, and simple to send.

A sample of 1.5 inches consisting of about 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a specimen of 150mg is suggested. We advise weighing the sample on a jeweler's scale. If scalp hair isn’t available, a comparable amount of body hair may be taken. When we mention head hair, we mean scalp hair; body hair refers to other types (facial, axillary, etc.).

Process Overview

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

Accessioning consists of the preliminary processing of a sample within a lab's framework. It involves ensuring the sample was properly sealed and transported, issuing a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening involves a preliminary assessment for drugs of abuse. Although Screening is a cost-effective means to exclude drug presence in the majority of samples, a positive result in Screening must be verified for court admissibility. Samples showing presumptive positives during Screening necessitate a secondary confirmation.

If a sample receives a presumptive positive during Screening, additional hair is extracted from the original specimen and prepared for Extraction. At this phase, drugs are derived from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.

For any positive screening result, Confirmation is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as required. The entire laboratory operation from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use up to 90 days, in contrast to urine tests which have a shorter detection period.
• Difficult to deceive: It is exceedingly challenging to manipulate a hair drug test, enhancing result accuracy.
• Delivers historical data: It provides an overview of drug use over time, not merely recent consumption.

Limitations:

• Cannot detect immediate use: Approximately 5-7 days are needed for drugs to become traceable in hair.
• Expense: Hair drug tests typically cost more than other drug testing approaches.
• Result variances: Variables such as hair color and personal hair growth differences can influence the level of drug metabolites in hair.

Note: Although termed "hair follicle tests", the analysis is performed on 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.
