In the ever-evolving landscape of healthcare, rapid and accurate diagnostics are crucial, especially for respiratory infections caused by viruses such as SARS-CoV-2, influenza, and RSV. The LyoSens qPCR bundle, which includes the LyoSens SARS-CoV-2 & Flu & RSV Detection Lyophilized RT-qPCR Kit, VTFOR fast extraction Nucleic Acid Transport (NAT) Medium, and ChainPro qPCR device by Vitrosens, offers a comprehensive solution for healthcare distributors and providers. This blog explores the components of this innovative bundle and its benefits in point-of-care settings.

LyoSens SARS‑CoV‑2 & Flu & RSV Detection Kit

The LyoSens Detection Kit is a cutting-edge tool designed for the in vitro diagnosis of SARS-CoV-2, influenza, and RSV nucleic acids from nasopharyngeal and oropharyngeal swabs. This lyophilized RT-qPCR kit simplifies the testing process by providing all necessary reagents in a single tube, ensuring ease of use and reducing the risk of contamination.

The kit targets specific genes in the SARS-CoV-2, influenza, and RSV genomes, utilizing FAM, ROX, and Cy5 channels for detection. Additionally, it includes an internal control (RNase P gene) monitored through the HEX channel, ensuring the validity of test results. The shelf life of the kit is 24 months, and it should be stored at room temperature, making it convenient for healthcare settings.

Key features of the LyoSens Detection Kit include:

• Broad Detection Spectrum: Targets specific gene regions unique to SARS‑CoV‑2, influenza, and RSV.
• Integrated Controls: Includes an internal control (e.g., the RNase P gene) to ensure the validity of each test run.
• Stability and Ease of Storage: With a shelf‑life of 24 months and room temperature storage, the kit is both cost‑effective and convenient for point‑of‑care applications.
• Simplified Workflow: All required reagents are provided pre‑aliquoted in a single tube, reducing the complexities of multi‑step assays.

The streamlined process improves diagnostic turnaround while ensuring high sensitivity and specificity in detecting respiratory pathogens. This makes it an indispensable tool for settings where rapid decision‑making is critical for patient care.

VTFOR Fast Extraction Nucleic Acid Transport (NAT) Medium

Fast nucleic acid extraction using Nucleic Acid Transport (NAT) Medium is designed to simplify and accelerate sample processing before PCR. The medium stabilizes and preserves nucleic acids while inactivating pathogens, allowing for direct use in PCR with minimal processing. Here’s a streamlined approach:

Steps for Fast Extraction Using NAT Medium for PCR:

1. Sample Collection & Inactivation

• Collect the clinical sample (e.g., nasopharyngeal or oropharyngeal swab).
• Place the swab into the NAT medium. This step immediately inactivates pathogens while preserving RNA/DNA integrity.

2. Incubation & Lysis (If Required)

• Some NAT media allow direct use, while others require brief incubation (e.g., heat at RT for 15 min) to enhance lysis and RNA release.

3. Centrifugation (Optional for Purification)

• Spin down the sample at 3,000-5,000 rpm for 1-2 minutes to remove debris if necessary.

4. Direct Use in qPCR

• Pipette a small volume (e.g., 5-10 µL) of the NAT medium sample into the qPCR reaction mix.
• Since the medium stabilizes nucleic acids, additional purification steps like RNA extraction kits may not be needed.

Advantages of Using NAT Medium for Fast Extraction:

• Eliminates lengthy RNA extraction steps.
• Reduces contamination risks.
• Compatible with direct-to-PCR workflows.
• Preserves nucleic acid integrity for reliable qPCR results.

Practical Considerations for Implementation and Integration

While technology and innovation drive advancements in diagnostics, seamless integration into real-world clinical settings is equally essential. The LyoSens qPCR bundle offers a powerful solution for respiratory pathogen detection, but its effective adoption depends on several practical considerations.

One of its key advantages is room-temperature storage with a 24-month shelf life, reducing the logistical burden of cold storage. However, maintaining reagent efficacy requires strict adherence to storage and handling guidelines. Additionally, routine maintenance and calibration of the ChainPro qPCR device are vital to ensuring consistent performance and high-quality diagnostic results over time.

For larger laboratories and centralized healthcare facilities, integration with Laboratory Information Management Systems (LIMS) can streamline data management, enhance reporting efficiency, and optimize resource utilization. Furthermore, proper training for healthcare providers is crucial to ensuring accurate test execution, reducing variability, and maintaining the reliability of results.

To prevent contamination and ensure reproducibility, facilities should implement strict protocols, including dedicated equipment, separate pre- and post-PCR workspaces, and meticulous handling of reagents. By addressing these practical considerations, healthcare providers can maximize the efficiency and reliability of the LyoSens qPCR bundle, transforming it from a technological innovation into a seamlessly adaptable solution for modern diagnostic needs.
