Hair Follicle Drug Testing - Wardell, MO

What it is, How it works

Hair analysis is recognized as an effective means for detecting alcohol and drug consumption. It captures a longitudinal timeline of substance use by embedding biomarkers within the strands of hair. When obtained proximate to the scalp, hair offers an estimated three-month detection span for substances. The collection process is straightforward, though tampering is challenging, and it’s convenient for shipping.

A specimen measuring 1.5 inches with about 200 hairs (equivalent to a #2 pencil) nearest to the scalp yields 100mg, which is ideal for initial tests and confirmatory tests. For tests such as EtG, add-ons, or beyond 10 panels, 150mg is advisable. Using a jeweler’s scale is suggested for precise measurement. Should scalp hair be inaccessible, a comparable quantity of body hair is acceptable. "Head hair" pertains solely to scalp hair, whereas "body hair" covers all other types (facial, axillary, so forth).

Process Overview

The primary phases in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a sample into a lab's system. This phase ensures samples are appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from an electronic chain of custody.

Screening consists of a swift preliminary scan for abuse substances. While it's an economical approach to eliminate most samples' drug use, legally admissible results require confirmatory screenings for any positive indications.

In cases where a sample tests positive during Screening, additional hair is retrieved from the original sample for Extraction preparation. This phase involves extracting drugs at significantly lower concentrations compared to other methods (e.g., urine or saliva), underscoring the complexity of hair drug testing.

The Confirmation process of a positive Screening employs methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before Confirmation when necessary. The laboratory process, from Accessioning through Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug usage up to 90 days, relative to urine tests with shorter detection periods.
• Resistance to tampering: The complexity of altering a hair drug test enhances result fidelity.
• Tracks historical usage: It can outline a timeline of drug usage history rather than recent usage alone.

Limitations:

• Delayed detection: Drugs require around 5-7 days to be detectible in hair fibers.
• Expense: Generally, hair drug tests incur higher costs than alternative drug testing approaches.
• Result variability: Elements like hair color and personal hair growth rates may impact drug metabolite concentrations.

Note: Commonly misconceived as "hair follicle tests," the assessment targets the hair shaft, not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Wardell, MO, hair follicle testing surpasses traditional urine tests due to superior accuracy and reliability. While urine tests cover recent drug activity, they're prone to tampering.

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.
