Hair Follicle Drug Testing - Bridgewater, VA

What it is, How it works

Viewed as a robust means for identifying alcohol and drug intake, hair testing offers a detailed timeline by capturing biomarkers within the hair strand as it grows. Hair sourced near the scalp can reveal drug and alcohol usage over roughly three months. Collecting hair is a straightforward process, with low risk of alteration and easy transport.

Gathering a 1.5-inch segment of about 200 hair strands (roughly #2 pencil-sized) nearest the scalp provides 100mg of hair, optimal for both screening and confirmation procedures. For EtG, additional analyses, and/or tests beyond ten panels, it is suggested to obtain 150mg of the specimen. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not present, an equivalent volume of body hair is permissible. The term head hair pertains exclusively to scalp hair. Body hair encompasses other hair types (such as facial, axillary, etc.).

Process Overview

The procedure for processing a drug test result in a laboratory is comprised of Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample enters a lab’s system for initial handling. This involves ensuring the sample is sealed and sent appropriately, assigning it a random LAN (Laboratory Accessioning Number), and completing supplemental data entry, if not provided by an electronic chain of custody system.

Screening entails a preliminary evaluation for drug abuse substances. While it serves as an economical approach to exclude drug presence in most samples, positive screens necessitate verification for court validity. Any samples yielding presumptive positive results during Screening require further confirmation.

For samples showing presumptive positivity in Screening, additional hair is extracted from the initial sample for Extraction. In this phase, drug compounds are isolated from hair at significantly lower concentrations compared to other techniques (like urine or oral fluid), making hair drug screening notably challenging.

GC/MS, GC/MS/MS or LC/MS/MS techniques are employed for the Confirmation of any positive screening findings. Any samples with presumptive positivity undergo necessary washing prior to confirmation. From Accessioning to Confirmation, the laboratory procedure is evaluated under the CAP (College of American Pathologists) Hair criteria and adheres to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Able to reveal drug usage for up to 90 days, hair tests offer a wider window compared to urine tests which have a narrower detection timeline.
• Resistant to manipulation: Hair drug tests are intricate to falsify, ensuring result precision.
• Tracks usage history: It offers an outline of drug use over a prolonged span rather than just recent usage.

Limitations:

• Lacks immediate detection: Drugs take roughly 5-7 days post-use to become traceable in hair.
• Expense: Hair drug assessments tend to be pricier than alternate testing methods.
• Result variation: Drug metabolite levels in hair may fluctuate due to hair color and personal hair growth differences.

Note: Commonly termed "hair follicle tests", the examination targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Bridgewater, VA, the former stands out due to its superior detection reliability. Unlike urine tests, hair analyses provide a broader detection window, uncovering past drug use over an extended period.

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.
