Hair Follicle Drug Testing - Noonday, TX

What it is, How it works

Hair testing is increasingly regarded as an effective method for the identification of narcotic and alcohol consumption. Hair encapsulates a documented history of alcohol and other substances by securing biomarkers within its growing fibers. When taken near the scalp, hair can offer nearly a 3-month timeframe for detecting alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.

Collecting a 1.5-inch segment consisting of approximately 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample size for both screening and verification. For EtG, add-ons, and tests extending beyond 10 panels, 150mg of hair is suggested. It is advisable to use a jeweler’s scale to weigh the sample. If head hair is not available, an equivalent quantity of body hair can be used. 'Head hair' specifically refers to scalp hair only, whereas 'body hair' encompasses all other hair types (e.g., facial, axillary, etc.).

Process Overview

The laboratory process for drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into a laboratory's system. This step includes ensuring the sample's seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry that might be absent from an electronic chain of custody system.

Screening is a preliminary check for drug abuse substances. Even though Screening offers a budget-friendly way to rule out drug use for most specimens, a positive screen requires confirmation to be court admissible. Presumptive positives in Screening necessitate further confirmation.

In case a sample is presumptively positive at the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. During this phase, substances are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), which accounts for the complexity of hair drug testing.

Confirmation of any positive in the Screening process is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample undergoes washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the ability to identify drug use up to 90 days, whereas urine tests cover a shorter period.
• Hard to manipulate: The difficulty to deceive a hair drug test enhances result accuracy.
• Offers usage history: It reveals a pattern of drug use over time, not merely recent consumption.

Limitations:

• Recent use undetectability: Detecting drugs using hair takes approximately 5-7 days.
• Expense: Hair drug tests generally cost more compared to other drug testing methods.
• Result variability: Elements like hair color and individual hair growth rates can impact drug metabolite concentration in the hair.

Note: Though often termed as "hair follicle tests", the test analyzes 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.
