Hair Follicle Drug Testing - Rolla, MO

What it is, How it works

Hair evaluation has emerged as an effective instrument for identifying substance and alcohol consumption. Hair offers a prolonged record of alcohol and other substances by capturing biomarkers within the fibers of evolving hair strands. When taken close to the scalp, it can yield approximately a 3-month detection period for alcohol and other drugs. Hair collection is straightforward, fairly tamper-resistant, and convenient to transport.

A 1.5-inch length of around 200 hair strands (comparable to the width of a #2 pencil) near the scalp will provide 100mg of hair, the optimal sample for analysis and confirmation. For EtG, additional assessments, or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest weighing the sample using a jeweler's scale. If scalp hair isn't accessible, a comparable quantity of body hair may be gathered. The term "head hair" specifically refers to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a laboratory's system. This step includes ensuring the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening serves as an initial rapid evaluation for detectable drugs. While Screening efficiently rules out drug use in most samples, a positive screen necessitates confirmation for court proceedings. Samples that are presumptively positive during Screening mandate a follow-up confirmation.

If a sample tests presumptively positive during Screening, additional hair is sourced from the original specimen and prepared for Extraction. In this phase, substances are extracted from hair at a significantly lower concentration than through other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology.

Any positive screening result is verified via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair category and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can detect drug use for up to 90 days, in contrast to urine tests which offer a shorter detection timeframe.
• Hard to falsify: It's extremely challenging to deceive a hair drug test, resulting in more reliable results.
• Historical insights: It provides a pattern of drug usage over time, not just recent activity.

Limitations:

• Incapable of identifying recent use: Approximately 5-7 days are required for substances to be traceable in hair.
• Expensive: Hair drug tests typically carry a higher price compared to other testing methods.
• Result variability: Elements such as hair color and individual growth variations can influence drug metabolite concentrations in hair.

Note: Although commonly termed as "hair follicle tests", the test examines 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.
