Hair Follicle Drug Testing - Weeping Water, NE

What it is, How it works

Acknowledged as a formidable means for identifying substance use, hair analysis tracks drugs and alcohol over time by embedding biomarkers within the fibers of the hair as it grows. Hair taken near the scalp offers a detection span reaching up to three months for various substances. It's easy to gather, not easily tampered with, and straightforward to transport.

A 1.5-inch sampling encompassing roughly 200 hair strands (comparable to the width of a #2 pencil) nearest the scalp delivers 100mg of hair, which is ideal for initial and confirmatory testing. For EtG, additional tests, or panels exceeding ten, a 150mg sample is advised. We advocate for using a jeweler’s scale for precise measurement. In cases lacking scalp hair, a proportional quantity of body hair may be used. References to head hair indicate only scalp hair, whereas body hair includes all other forms (such as facial, axillary hairs).

Process Overview

The systematized laboratory sequence for a drug test result comprises Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary acceptance of a sample within a lab's framework. It certifies that the sample was properly sealed and sent, connects it with a random LAN (Laboratory Accessioning Number), and finalizes any data entry not captured by an electronic chain of custody.

Screening acts as a rapid preliminary assessment for substance presence. While this process is cost-efficient to eliminate drug intake from most samples, a positive result demands subsequent confirmation to be valid legally. Presumptive positives identified during Screening necessitate further verification.

Should a sample yield a presumptive positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. This phase involves removing drugs from hair at a lower concentration relative to other methods (including urine or oral fluids), underscoring the complexity of hair testing.

Confirmation of any positive determination from screening proceeds using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples marked as presumptive positive undergo washing before confirmation, if necessary. The comprehensive lab processes from Accessioning through Confirmation adhere to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair tests monitor drug use for up to 90 days, surpassing the shorter duration offered by urine tests.
• Harder to manipulate: The difficulty in falsifying a hair test enhances the reliability of the results.
• Shows usage trends: It reveals broader patterns of substance use over time, opposed to just recent usage.

Limitations:

• Incapable of spotting current use: Detecting drugs in hair requires approximately 5-7 days.
• Expense: Hair tests generally incur greater costs than alternative testing approaches.
• Result variability: Elements like hair color and individual hair growth differences impact drug metabolite concentrations in hair.

Note: Though often called "hair follicle tests", the procedure evaluates the hair strand, not the follicle within 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.
