Hair Follicle Drug Testing - Centenary, VA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The hair traps biomarkers as it grows, offering a historical record of substance use over time. Collected near the scalp, hair samples can offer detection for drugs and alcohol for up to roughly 3 months. It is easy to collect, hard to tamper with, and simple to send.

A sample measuring 1.5 inches of around 200 strands (equivalent in width to a #2 pencil) taken nearest to the scalp yields 100mg, the perfect amount for testing and verification. For EtG, additional testing, or panels exceeding 10, 150mg is advised. It's recommended to weigh the hair sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair covers other types like facial or axillary hair.

Process Overview

The primary stages in lab processing of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample within a lab's system. This step validates that the sample is properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and incorporates any supplementary data not available through an electronic chain of custody.

Screening entails an initial swift examination for drug abuse presence. While cost-effective for eliminating drug use in the majority of samples, a positive screen requires verification to be legally valid. Any samples flagged as positive in Screening necessitate further confirmation.

Should a sample indicate a positive result during Screening, additional hair from the initial sample is prepared for Extraction. This phase ensures drugs are extracted from hair at significantly lower levels than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All positive samples are cleansed before confirmation as required. The complete lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use for up to 90 days, unlike urine tests with shorter detection durations.
• Difficult to falsify: The precision of hair drug tests makes them almost impossible to deceive.
• Shows historical use: It reflects a wider pattern of substance usage, not just recent incidents.

Limitations:

• Cannot detect immediate use: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair testing usually incurs a higher cost than other testing methods.
• Result variations: Differences such as hair color and individual hair growth rates can influence drug metabolite levels in hair.

Note: Commonly called "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outperform urine testing in Centenary, VA? It's simple: the extended detection window and superior reliability make hair testing a valuable tool.

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.
