Flu/RSV computer generated depiction.

Fast, accurate and reliable detection of Flu A, Flu B and/or RSV in one test

The Need

an ill woman listens to a physician
  • Influenza and RSV are major causes of hospitalizations of both adults and children.1
  • Influenza and RSV often present with similar symptoms, making it difficult to differentiate between the two infections2
  • Sensitivities of rapid antigen detection tests (RADTs) for influenza and RSV range from 50–70% 3,4
  • Reported sensitivity of RADTs for RSV is as low as 26%5
  • Manufacturers of RADTs may recommend confirming Flu negative results with RT-PCR or culture.3
  • Rapid RSV tests may have age limitations in their claims6

The Solution

a male and a female researchers scanning cepheid test cartridges
  • Accurate and reliable detection of Flu A, Flu B and RSV in as soon as 20 minutes* for patients of all ages
  • Provides PCR results to support clinical decision‑making related to patient management and infection‑control considerations
  • molecular testing has been shown to support laboratory workflow efficiency in integrated health systems.7

* With early assay termination (EAT) for positive Flu or for positive RSV only. Reporting negatives and combined Flu and RSV results in approximately 30 minutes.

The Impact

a smiling female doctor attends an elderly woman
Single‑test workflow that supports on‑demand, random‑access testing flexibility. Combine performance with the capability to run other Xpert® tests on Cepheid’s GeneXpert® system may support laboratory workflow efficiency in certain testing environments..

Be Proactive
  • Achieve fast results to support patient management
  • Early assay termination option: deliver positive results for Flu or RSV only reporting in as soon as approx. 20 minutes* and negative results in approx. 30 minutes
  • Quickly deliver results for informed treatment decisions
