Hair Follicle Drug Testing - Badin, NC

What it is, How it works

Hair testing is now acknowledged as an effective method for identifying drug and alcohol usage. Hair can show a historical timeline of alcohol and drug consumption by capturing biomarkers within the hair's fibers as it grows. When obtained near the scalp, hair can offer up to a three-month detection period for alcohol and drugs. It is easy to gather, challenging to tamper with, and convenient to transport.

A 1.5-inch section consisting of about 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for both screening and validation. For EtG, additional tests, and evaluations exceeding 10 panels, a sample of 150mg is advised. Ensuring the specimen's weight on a jeweler’s scale is recommended. If scalp hair is not accessible, an equivalent quantity of body hair can be used. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the preliminary processing of a sample in a laboratory’s system. This step involves confirming that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any other required data entry absent from an electronic chain of custody system.

Screening includes a preliminary rapid assessment for drugs of abuse. While Screening offers a cost-efficient means to eliminate drug use in most samples, a positive screening result requires confirmation to be valid for legal proceedings. All presumptive positive samples during Screening necessitate a secondary confirmation.

Should a sample be presumptively positive during the Screening phase, additional hair is retrieved from the initial sample for preparation in the Extraction phase. Here, drugs are extracted from hair at a significantly lower concentration compared to alternative methodologies (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Positively screened samples are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptive positive are cleansed before confirmation if needed. The entire laboratory procedure, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair protocol and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, which surpasses the timeframe of urine tests.
• Reduced likelihood of cheating: It is quite challenging to deceive a hair drug test, enhancing the accuracy of the outcomes.
• Depicts historical usage: Provides a timeline of drug usage over a prolonged period, not restricted to current consumption.

Limitations:

• Inability to detect immediate use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests are typically more costly than other drug testing techniques.
• Variable outcomes: Result variation can stem from factors like hair color and individual differences in hair growth affecting drug metabolite concentration.

Note: Though commonly called "hair follicle tests", the analysis examines the hair strand rather than the follicle itself under 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.
