Company context

Bluejay Diagnostics, Inc. is a medical diagnostics company focused on improving patient outcomes using its Symphony™ System, a cost-effective, rapid, near-patient testing system for sepsis triage and monitoring of disease progression. Bluejay does not yet have regulatory clearance for the Symphony™ System, and we will need to receive regulatory authorization from the U.S. Food and Drug Administration before Symphony™ can be marketed as a diagnostic product in the United States. Bluejay’s first product candidate, an IL-6 Test for sepsis, is designed to provide accurate, reliable results in approximately 20 minutes from ‘sample-to-result’ to help medical professionals make earlier and better triage/treatment decisions. More information is available at www.bluejaydx.com.
