Delivers accurate and timely results that optimizes fast treatment decisions

The Need

To accurately diagnose pharyngitis caused by Group A Streptococcus (GAS) due to increasing incidence and prevalence globally.
  • Annually, 616 million people have GAS pharyngitis, more than 18.1 million people develop severe GAS disease and more than 517,000 people die due to severe GAS disease1
Reduce overuse of antibiotics for the treatment of pharyngitis.
  • Literature shows 37% of children who presented with pharyngitis tested positive for GAS, however 56% of visits were associated with antibiotic prescriptions. Similarly, 18% of adults presented with pharyngitis caused by GAS, but 72% were treated with antibiotics.2

The Solution

  • Cepheid provides on-demand testing for Group A Strep in as soon as 18 minutes.*
  • Careful selection of the target gene.
  • Delivers timely results to support clinical decision-making without the need for culture confirmation of negative.#
* Full test runtime is 24 minutes. Positive results available in as soon as 18 minutes with early assay termination.
# Additional follow-up testing by culture is required if the Xpert Xpress Strep A test result is negative and clinical symptoms persist, or there is an outbreak of acute rheumatic fever (ARF).

The Impact

  • Accurate diagnosis of GAS supports antimicrobial stewardship initiatives and may reduce the amount of patients inappropriately prescribed antibiotics.
  • May support testing efficiency and potential cost savings by reducing follow‑up culture testing in certain settings.3,#
  • In clinical practice, treating an infected person with an appropriate antibiotic generally prevents the spread of infection and reduces the risk of post‑infectious complications, such as rheumatic fever and acute glomerular nephritis.
