Hair Follicle Drug Testing - Rose Tree, PA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair holds a prolonged history of alcohol and drugs by encasing biomarkers within the fibers of its growing strands. When samples are taken close to the scalp, they can offer an approximate 3-month window for detecting alcohol and drug use. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.

A sample measuring 1.5 inches with approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest the scalp yields 100mg, an optimal amount for screening and verification. For EtG tests, additional testing, and/or tests exceeding 10 panels, a 150mg sample is advised. The specimen should be weighed using a jeweler’s scale. If scalp hair is unavailable, equivalent body hair can be collected. "Head hair" refers specifically to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the initial processing of a sample into a lab’s system, which involves ensuring that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening is an initial rapid check for substances of abuse. While Screening presents a cost-effective way to dismiss drug usage for most samples, a positive screen needs confirmation to be valid in court. Samples showing a presumptive positive in Screening necessitate further confirmation.

If a sample tests presumptively positive in the Screening phase, additional hair is retrieved from the original specimen and readied for Extraction. During this stage, drugs are extracted from hair at significantly lower concentrations than in other testing methods (e.g., urine or oral fluid), which is why hair drug screening is one of the most challenging methodologies to execute.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation as necessary. The full lab process from Accessioning to Confirmation is scrutinized 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 reveal drug use up to 90 days, whereas urine tests have a briefer detection period.
• Limited opportunities for tampering: Cheating a hair drug test is very challenging, enhancing result accuracy.
• Offers usage history: It unveils a drug use pattern across time, rather than merely recent use.

Limitations:

• Cannot detect recent use: About 5-7 days are necessary for drugs to become noticeable in hair.
• Expense: Typically, hair drug tests are costlier compared to other drug testing methods.
• Result variations: Factors like hair color and individual growth differences can impact drug metabolite concentration in hair.

Note: The term "hair follicle tests" is often used, though the test evaluates the hair strand, not 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.
