Hair Follicle Drug Testing - Winchester, VA

What it is, How it works

Hair analysis has emerged as a formidable method for identifying drug and alcohol consumption. The hair captures long-term indicators of alcohol and other substances by embedding biomarkers within the strands of the hair as it grows. When harvested near the scalp, hair can offer up to a roughly 3-month timeframe for detecting alcohol and other drugs. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.

A 1.5-inch portion of around 200 hairs (approximately the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for examination and authentication. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of the hair is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be utilized. References to head hair strictly mean scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The principal stages in processing a drug test in the laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary integration of a specimen into a laboratory’s framework. This involves confirming the sample’s seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not furnished by a digital chain of custody mechanism.

Screening entails a preliminary brief examination for signs of drug misuse. While Screening is economical for dismissing drug usage in most samples, a positive screen requires confirmation for legal admissibility. Samples presumptively positive in Screening need subsequent confirmation.

Should a sample be presumptively positive during the Screening stage, additional hair is taken from the initial sample and set up for Extraction. In this step, drugs are separated from hair at a far lower concentration than other methods (e.g., urine or oral fluid), which is why hair drug analysis is the most intricate method to execute.

Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS or LC/MS/MS. All samples considered presumptively positive are washed before confirmation as necessary. The entire lab process from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can detect drug use for as long as 90 days, in contrast to urine tests that have a shorter detection period.
• Challenging to manipulate: Cheating a hair drug test is very difficult, enhancing result reliability.
• Yields historical insights: It can highlight a usage pattern of drugs over an extended time frame, not merely recent instances.

Limitations:

• Incapable of identifying recent use: Approximately 5-7 days are needed for drugs to manifest in hair.
• Expense: Hair drug testing is generally costlier than other testing methods.
• Result variability: Factors like hair color and individual hair growth variations can influence the concentration of drug metabolites in hair.

Note: While commonly called "hair follicle tests", the analysis actually examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
