cobas^® Strep A Assay

Strep A is responsible for over 600 million global cases of acute pharyngitis annually.¹ On a global scale, group A Streptococcus (GAS) is a leading cause of morbidity and mortality.² Clinical symptoms of GAS infection overlap with other diseases. Providing an early and accurate diagnosis enables appropriate prescription of antibiotics which can aid in reducing further complications of Strep A.³

The cobas^® Strep A Nucleic acid test for use on the cobas^® Liat^® System is a real-time polymerase chain reaction (PCR) test for the detection of Strep A in throat swab specimens from patients with signs and symptoms of pharyngitis

cobas^® Strep A offers:

• Definitive Strep A PCR results in 15 minutes, for confident treatment decisions
• No confirmation needed, enabling optimized patient workflow
• Informed prescribing to support antibiotic stewardship and patient confidence

Help patients get the treatment and relief they need faster with the reliable accuracy of the cobas^® Strep A Test for use on the cobas^® Liat^® System. A growing menu of assays, together with the small, swift, simple and secure analyzer, and the cobas^® infinity POC solution, form the total point-of-care PCR solution - a revolution in POC efficiency and patient satisfaction.

Signs & Symptoms

Strep score based on clinical manifestations

Could lead to incorrect antibiotic treatment

Unnecessary antibiotics for empirical
treatment based on clinical suspicion.

Not prescribing antibiotics because
clinical suspicion was not high enough,
but it was in fact Strep A

Conventional methods
