FebriDx®: A Rapid Point-of-Care Test for Differentiating Bacterial and Viral Respiratory Infections

Acute respiratory infections (ARIs) are one of the most common reasons people visit a doctor. Symptoms such as fever, cough, sore throat, and fatigue can be caused by either bacteria or viruses, but these infections often look very similar. Because of this, it can be difficult for healthcare providers to determine the exact cause based on symptoms alone.

The FebriDx® Rapid Test is designed to help solve this challenge. It is a rapid point-of-care test that helps healthcare professionals distinguish between bacterial and viral respiratory infections in approximately 10 minutes. By providing quick and reliable information, FebriDx supports better clinical decisions and promotes responsible antibiotic use.


What Is FebriDx®?




FebriDx® is a rapid diagnostic test used to help differentiate bacterial and viral causes of acute respiratory infections. It is intended for patients 2 years of age and older who have symptoms consistent with a community-acquired respiratory infection.

Unlike traditional laboratory testing, FebriDx uses a simple fingerstick blood sample and does not require complex laboratory equipment. The test can be performed during a patient visit, allowing healthcare providers to receive results quickly and make informed treatment decisions.


Why Is It Important to Differentiate Between Bacterial and Viral Infections?


Many respiratory infections have nearly identical symptoms. Patients with either a bacterial or viral infection may experience:

  • Fever

  • Sore throat

  • Cough

  • Fatigue

  • Body aches

  • Nasal congestion

Because the symptoms overlap, healthcare providers may find it difficult to determine whether antibiotics are necessary.

Antibiotics are effective against bacterial infections but do not work against viral infections. Prescribing antibiotics when they are not needed can contribute to antibiotic resistance and expose patients to unnecessary side effects.

A rapid test like FebriDx helps reduce uncertainty and supports more appropriate treatment decisions.


How Does FebriDx Work?





FebriDx works by measuring two important biomarkers from a small fingerstick blood sample:


C-Reactive Protein (CRP)


CRP is a marker of inflammation that often increases during bacterial infections. Elevated CRP levels may indicate that the body's immune system is responding to a bacterial illness.


Myxovirus Resistance Protein A (MxA)


MxA is a protein produced by the body's immune system in response to viral infections. Elevated MxA levels suggest that the infection is likely caused by a virus.

By evaluating these two biomarkers together, FebriDx helps healthcare professionals determine whether the patient's respiratory infection is more likely bacterial or viral.


Results in Approximately 10 Minutes




One of the biggest advantages of FebriDx is its speed.

The test provides actionable results in around 10 minutes, allowing healthcare providers to discuss treatment options during the same patient visit.

Fast results help reduce delays in diagnosis and improve the overall patient experience.


Simple Point-of-Care Testing


FebriDx is designed to be easy to perform in outpatient settings.

The testing process includes:

  1. Collect a small fingerstick blood sample.

  2. Apply the sample to the test device.

  3. Allow the test to develop.

  4. Read the results after approximately 10 minutes.

Because no additional equipment is required, the test fits easily into busy healthcare practices.


Supports Better Antibiotic Stewardship


One of the most important benefits of FebriDx is its role in supporting responsible antibiotic prescribing.

Many respiratory infections are caused by viruses, yet antibiotics are sometimes prescribed when they are unlikely to provide any benefit.

By helping identify whether an infection is bacterial or viral, FebriDx can support healthcare providers in making more informed prescribing decisions.

Responsible antibiotic use helps:

  • Reduce unnecessary antibiotic prescriptions.

  • Support antibiotic stewardship programs.

  • Lower the risk of antibiotic resistance.

  • Reduce unnecessary medication exposure.

  • Improve overall patient care.


Reliable Clinical Performance


Clinical studies have shown that FebriDx provides strong sensitivity and specificity for differentiating bacterial and viral respiratory infections.

Its ability to identify clinically significant infections gives healthcare providers additional confidence when evaluating patients with respiratory symptoms.

This reliable performance makes FebriDx a valuable diagnostic aid in outpatient care.


Ideal for Outpatient Healthcare Settings


FebriDx is suitable for a wide variety of healthcare environments, including:

  • Primary care clinics

  • Family medicine practices

  • Urgent care centers

  • Walk-in clinics

  • Community healthcare facilities

  • Outpatient medical centers

Its rapid turnaround time and simple testing procedure help improve workflow while supporting timely patient care.


Benefits for Healthcare Professionals

Healthcare providers need diagnostic tools that are accurate, efficient, and easy to use.

FebriDx offers several important advantages:

  • Results in approximately 10 minutes.

  • Uses a simple fingerstick blood sample.

  • No additional instruments required.

  • Helps distinguish bacterial from viral infections.

  • Supports informed treatment decisions.

  • Encourages responsible antibiotic prescribing.

  • Easy to perform at the point of care.

These benefits make it easier for clinicians to evaluate patients during a single visit.


Improving Patient Care


Patients benefit when healthcare providers have rapid access to reliable diagnostic information.

With FebriDx, patients may receive:

  • Faster clinical assessment.

  • More appropriate treatment recommendations.

  • Reduced unnecessary antibiotic exposure.

  • Greater confidence in their diagnosis.

  • Improved overall healthcare experience.

Early and accurate diagnosis helps both patients and healthcare providers make better decisions.


Why Choose FebriDx®?


FebriDx combines speed, simplicity, and clinical value in one easy-to-use diagnostic test. By measuring both CRP and MxA biomarkers, it helps distinguish between bacterial and viral respiratory infections within minutes.

Its ability to support appropriate antibiotic use makes it an important tool for modern outpatient healthcare, especially during seasons when respiratory illnesses are common.
