Reducing antibiotic use, one sinus at a time

The Problem

Every year, over 30 million patients in the US visit their GP for a suspected case of Sinusitis.

80% of these patients will be prescribed antibiotics

Less than 10% have bacterial sinusitis (and therefore less than 10% actually require antibiotics) 

Unnecessary antibiotic use can cause individual side effects and contributes to the rising tide of antibiotic-resistant infections. 

About Diagnose

Diagnose provides a simple, quick, non-invasive test that can be conducted in your GP office. The test provides a simple yes/no guidance on whether sinusitis is bacterial or viral - and therefore whether antibiotics should be prescribed.
