Hair Follicle Drug Testing - Alsace Manor, PA

What it is, How it works

Hair testing is recognized as an effective method for detecting drug and alcohol use. Hair can document a prolonged history of alcohol and drug consumption by locking in biomarkers within the strands of hair as they grow. When hair is taken near the scalp, it offers a detection window for drugs and alcohol lasting up to roughly 3 months. Collecting hair is straightforward, not easily tampered with, and simple to mail.

A 1.5-inch section consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter) near the scalp yields 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, or tests exceeding 10 panels, a specimen weighing 150mg is advised. It's advisable to measure the specimen on a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be utilized. By "head hair," we mean exclusively scalp hair. "Body hair" refers to any other hair types (such as facial hair, axillary hair, etc.).

Process Overview

The process of handling a drug test result in a laboratory is divided into four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into the laboratory's system. This step includes ensuring the sample was appropriately sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry missing from an electronic chain of custody system.

Screening serves as a preliminary scan for identifying drugs of abuse. While it efficiently eliminates drug use in the majority of specimens, a positive screening result requires confirmation for legal admissibility. Samples that are tentatively positive at the Screening stage need further confirmation.

Should Screening indicate a tentative positive, more hair is drawn from the original specimen and processed for Extraction. During Extraction, drugs are withdrawn from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), thus making it a challenging method to execute.

Positive results in the screening phase are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as tentatively positive are cleansed before undergoing confirmation, as necessary. Each stage from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug intake for up to 90 days, unlike urine tests, which have a shorter time frame.
• Hard to manipulate: Because it's challenging to deceive a hair drug test, results tend to be more reliable.
• Tracks past use: It reveals a pattern of drug consumption over extended periods, not only recent use.

Limitations:

• Cannot identify immediate use: Detection in hair takes about 5-7 days post-consumption.
• Expense: Hair drug testing generally costs more than other drug testing techniques.
• Potential result variations: Variables like hair color and individual growth rates can alter the concentration of drug metabolites in hair.

Note: Though commonly termed "hair follicle tests," the analysis focuses on 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.
