Hair Follicle Drug Testing - Manassas, GA

What it is, How it works

Hair testing is increasingly acknowledged for effectively identifying drug and alcohol usage. Hair serves as a comprehensive record of substance use, as it entraps biomarkers in the hair strand's fibers. When collected near the scalp, hair can reveal drug and alcohol consumption for up to a 3-month timeframe. The collection process is straightforward, tampering is relatively challenging, and shipment is uncomplicated.

A sample of 1.5 inches consisting of roughly 200 hair strands (approximately matching the width of a #2 pencil) from the scalp yields 100mg of hair, ideal for screening and validation. For EtG and supplementary or tests exceeding 10 panels, 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. If there's no scalp hair, a similar amount of body hair can be used. When mentioning head hair, it refers solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of drug tests involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step, integrating the sample into the laboratory system. This entails ensuring the sample is correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any missing data that wasn't supplied by an electronic chain of custody system.

Screening is a preliminary step to detect drug presence. Although Screening is an economical method to eliminate drug use in most samples, a positive result necessitates verification for legal acceptability. Positive indications in Screening must undergo additional confirmation.

For samples preliminarily positive in Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated at a significantly lower concentration than in other methods (e.g., urine or saliva), highlighting the complexity of hair drug analyses.

Confirmation of positive Screening results employs GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples with presumptive positive outcomes are cleansed before confirmation as required. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair classification and accredited according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can trace drug consumption for up to 90 days, contrasting with urine assessments which have a narrower detection span.
• Cheating deterrence: Tampering with hair drug assessments is notably challenging, ensuring more precise results.
• Historical insight: It can trace a pattern of drug usage over time, not just recent consumption.

Limitations:

• Incapable of detecting recent usage: Drugs take about 5-7 days to become noticeable in hair.
• Expense: Hair drug assessments are generally costlier than other testing approaches.
• Result discrepancies: Variations like hair pigmentation and individual hair growth rates can influence the concentration of drug markers in the hair.

Note: Although termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp

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.
