Hair Follicle Drug Testing - Rosedale, MD

What it is, How it works

Hair analysis is increasingly recognized for detecting drug and alcohol consumption. Hair captures a lengthy timeline of substances by embedding biomarkers within the strands as they grow. When hair is collected near the scalp, it offers roughly a 3-month window for detecting alcohol and drugs. Hair is straightforward to gather, not easily tampered with, and simple to transport.

A 1.5-inch segment of around 200 hair strands (comparable to the size of a #2 pencil) close to the scalp provides 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, and/or tests above 10 panels, a 150mg sample is advised. We suggest weighing the sample on a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair can be used. By head hair, we mean scalp hair only. Body hair denotes any other types (facial, axillary, etc.).

Process Overview

The processing of a drug test result in the lab includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into the laboratory workflow. This step involves checking that the sample was sealed and delivered correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any manual data entry not captured by an electronic chain of custody system.

Screening offers a preliminary evaluation for drug presence. While it is an economical way to identify drug usage for most samples, a positive result needs Confirmation for legal admissibility. Samples presumptively positive in Screening require secondary confirmation.

When a sample shows presumptive positivity in Screening, more hair is extracted from the initial sample and prepared for Extraction. This phase involves isolating drugs from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug analysis the most sophisticated process to execute.

Confirmation of a positive screen is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as needed. The laboratory process from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair qualifications and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can reveal substance use up to 90 days back, unlike urine tests which have a briefer detection span.
• Resistance to cheating: It is quite hard to manipulate a hair drug test, enhancing result accuracy.
• Traces usage history: Demonstrates a pattern of drug consumption over time, rather than only recent use.

Limitations:

• Incapable of detecting immediate use: Drugs take about 5-7 days to appear in hair.
• Expense: Compared to other methods, hair drug tests typically cost more.
• Variability in outcomes: Factors such as hair color and individual hair growth variances can influence the level of drug markers in hair.

Note: Although commonly termed "hair follicle tests", the analysis targets the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing outshines urine tests in Rosedale, MD due to its heightened accuracy and reliability in the detection of drugs.

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.
