Limitations of conventional diagnosis
Traditional detection methods—such as laboratory PCR or viral cultures—offer high sensitivity, but require specialized equipment, qualified technical personnel, and waiting times that can exceed 24 hours .
During an outbreak, these factors can create bottlenecks in emergency services and central laboratories , delaying the start of antiviral treatments or the isolation of infected patients.
Furthermore, the overlap of symptoms among respiratory viruses makes clinical diagnosis by observation insufficient. During periods of high incidence, distinguishing between influenza, COVID-19, and RSV based solely on clinical signs can be virtually impossible.
The solution: combined tests
POCT (Point of Care Testing) technology allows molecular or immunochromatographic tests to be performed directly at the point of care , offering results in less than 30 minutes .
This approach eliminates the need to send samples to the central laboratory, significantly reducing response times and enabling immediate action.
Ustar Biotechnology's MultNat combination tests represent a key evolution within this category. They allow for the simultaneous detection of multiple respiratory pathogens. in a single sample, facilitating a precise and rapid differential diagnosis.
Practical application in hospitals and clinics
During a respiratory outbreak, the ability to identify the responsible virus at the time of care has a direct impact on:
- Clinical decision-making: allows for the initiation of specific treatments or the application of appropriate isolation measures without delay.
- Hospital resource management: avoids unnecessary hospitalizations and reduces pressure on central laboratories.
- Epidemiological surveillance: provides immediate data on the prevalence of different respiratory viruses, facilitating the health response.
Ustar Biotechnologies Respiratory Combo Kit
Ustar Biotechnologies has developed a line of combined POCT kits designed for the rapid and simultaneous detection of the main respiratory viruses :
- Influenza A/B
- SARS-CoV-2
- Respiratory syncytial virus (RSV)

These kits are based on advanced molecular technologies that offer high sensitivity and specificity , comparable to laboratory tests, but with the advantage of obtaining results at the same point of care .
Their compact size and ease of use make them ideal for:
- Emergency and hospitalization services.
- Intensive care units.
- Clinics with high demand for respiratory diagnosis.
Furthermore, Ustar kits are designed to integrate easily into clinical workflows, ensuring fast results without compromising diagnostic quality.
Conclusion
Efficient management of respiratory outbreaks requires diagnostic tools that balance speed, accuracy, and accessibility .
Combined POCT tests offer an effective response to this need, allowing healthcare professionals to act quickly and confidently when faced with patients presenting with similar respiratory symptoms.
With solutions like the Combined respiratory kits from Ustar Biotechnologies , hospitals and clinics can reduce diagnosis times, improve patient care and optimize the health response to seasonal or emerging outbreaks.
