Xpert® Xpress Strep A

Qualitative real-time PCR test providing accurate detection of Group A Streptococcus in as soon as 18 minutes*

Xpert<sup>®</sup>&nbsp;Xpress&nbsp;Strep A

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 disease.1

Reduce overuse of antibiotics for the treatment of pharyngitis.

  • Based on recent literature, 37% of children presenting with pharyngitis tested positive for GAS, however 56% of visits were associated with antibiotic prescriptions. Similarly, 18% of adults presenting 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 produces quality results.
  • Delivering accurate and timely results optimizes fast treatment decisions and eliminates the need to perform culture confirmation of negative results.

* With Early Assay Termination for positive results. Refer to Package Insert Xpert Xpress Strep A 301-6574 Rev D, Package Insert Xpert Xpress Strep A CW 302-2294 Rev. A and 301-6127 Quick Ref Guide, Strep A Xpress

The Impact

  • Accurate diagnosis of GAS supports antimicrobial stewardship and may reduce the amount of patients inappropriately prescribed antibiotics.
  • Gain testing efficiencies and reduce costs by eliminating culture confirmation testing.3#
  • Reduce the risk of GAS complications such as rheumatic fever and glomerulonephritis.
  • Improve patient satisfaction with quicker time to result and appropriate prescriptions.

(3) Workflow studies conducted by Cepheid Solutions demonstrate that a throat culture confirmation workup costs~ $9.13 per culture. (Average cost includes reagents, labor cost and time). Data on file.
# 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).
