Hair Follicle Drug Testing - Paxtonia, PA

What it is, How it works

Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by storing biomarkers inside its fibers as it grows. When samples are taken near the scalp, hair can reveal a 3-month usage timeline for alcohol and drugs. It is straightforward to gather, less prone to tampering, and convenient to transport.

A sample measuring 1.5 inches with roughly 200 hairs (similar to the diameter of a #2 pencil) taken from the scalp amounts to 100mg, which is the optimum sample for testing and validation. For EtG, add-ons, or inspections that exceed 10 panels, 150mg is advised. The specimen can be weighed with a jeweler's scale. If scalp hair cannot be used, a comparable amount of body hair is permissible. When mentioning head hair, it specifically refers to scalp hair, while body hair encompasses other hair forms (facial, axillary, etc.).

Process Overview

The lab processing for drug testing comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial sample handling within the laboratory's system. This process checks that the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and includes any data entry that's absent from an electronic chain of custody record.

Screening provides a preliminary assessment for drugs of abuse. Although Screening offers an economical method to eliminate drug use from most samples, any positive results must be confirmed for legal acceptability. Presumptive positives through Screening necessitate secondary confirmation.

In the Screening process, if a sample tests presumptively positive, additional hair from the original sample is set aside for Extraction. Here, substances are extracted from hair at notably lower concentrations compared to other methods (like urine or oral fluid), highlighting that hair drug testing is a more complex procedure.

Confirmation of any positive screen is performed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation standards and the accreditation for ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection period: Hair tests detect drug use for as long as 90 days, which is longer than the window urine tests provide.
• Hard to deceive: Cheating on a hair drug test is exceedingly challenging, increasing result accuracy.
• Offers historical insight: It reveals a pattern of substance use over time rather than just recent usage.

Limitations:

• Doesn't identify recent use: Detection in hair takes about 5-7 days post-consumption.
• Expense: Hair drug screenings typically cost more than alternative testing methods.
• Result variability: Different factors like hair color and individual growth rates can influence drug metabolite levels found in hair.

Note: Commonly called "hair follicle tests", this test assesses the hair strand rather than 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. 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
