Hair Follicle Drug Testing - Countryside, VA

What it is, How it works

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair serves as a long-term archive of substances by embedding biomarkers within the strands' fibers as they grow. When extracted near the scalp, hair can reveal substance use within an approximately 3-month timeframe. Collecting hair is straightforward, less prone to tampering, and convenient to transport.

A 1.5-inch portion, roughly 200 strands (comparable to a #2 pencil), nearest to the scalp yields about 100mg, optimal for both screening and confirmation. For EtG, additional panels, or tests beyond 10 panels, 150mg is advisable. We suggest using a jeweler's scale to measure the specimen weight. If scalp hair cannot be obtained, a similar volume of body hair is acceptable. By 'head hair', we mean scalp hair only; 'body hair' implies all other types, such as facial or axillary hair.

Process Overview

The core stages in processing a drug test outcome in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a laboratory's system. This process entails verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry omitted from an electronic chain of custody system.

Screening consists of an initial swift examination for drug misuse. Although Screening is a cost-efficient means to negate drug presence for the majority of samples, a positive result requires confirmation for judicial admissibility. Presumptive positives during Screening necessitate further confirmation.

Should a sample show a positive screen, extra hair is sourced from the original sample for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), enhancing the complexity of hair drug analysis.

Positive screening confirmations utilize GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleansed before the confirmation phase as needed. The lab procedure from Accessioning to Confirmation undergoes evaluation under CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection duration: Hair drug assessments capture drug usage up to 90 days, surpassing shorter urine test periods.
• Enhanced accuracy: The difficulty in falsifying results increases reliability.
• Usage patterns: Offers insights into historical substance usage rather than just recent consumption.

Drawbacks:

• Absence of recent usage detection: Detecting drugs in hair takes around 5-7 days post-consumption.
• Expense: Generally pricier than alternative testing techniques.
• Result variability: Factors like hair color and individual growth variations influence drug metabolite concentration in hair.

Notably, while commonly called "hair follicle tests," the procedure targets the hair strand, not the follicle itself.

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. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
