Hair Follicle Drug Testing - Ayden, NC

What it is, How it works

Hair testing is regarded as a crucial method for identifying drug and alcohol consumption. By capturing biomarkers in the strands of growing hair, it offers an extended timeline of alcohol and drug use. When gathered near the scalp, hair can reveal substance usage over nearly a 3-month span. The collection of hair is straightforward, challenging to tamper with, and simple to ship.

A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation processes. For tests involving EtG, add-ons, or more than 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. In cases where scalp hair is unavailable, an equivalent amount of body hair can be used. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The lab processing of a drug test outcome includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning addresses the initial handling of a sample into the laboratory’s framework, ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry needed beyond the electronic chain of custody system.

Screening integrates an initial, swift assessment for substance abuse. Though cost-effective for dismissing drug use in numerous samples, any positive screen requires confirmation for court admissibility. Samples that test presumptively positive in Screening must undergo additional confirmation.

For presumptive positives during Screening, additional hair is retrieved from the original sample and set for Extraction, where drugs are isolated from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which renders hair drug screening particularly challenging.

Confirmation of positive screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptively positive samples are cleansed before confirmation as needed. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests can trace drug usage up to 90 days, while urine tests offer a shorter detection period.
• Hard to manipulate: Cheating on a hair drug test is challenging, yielding more reliable results.
• Historical data provision: It uncovers a trend of drug use over time instead of just recent usage.

Limitations:

• Inability to detect recent usage: Drugs become traceable in hair about 5-7 days following use.
• Expense: Hair drug tests generally cost more than alternative testing methods.
• Outcome variations: Elements such as hair color and individual hair growth differences can influence drug metabolite concentrations in the hair.

Note: The term "hair follicle tests" is somewhat misleading, as the analysis involves 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.
