Pathnostics is a global diagnostics solutions company specializing in key therapeutic areas, including urology, women’s health, gastroenterology and cancer.  The company has grown rapidly in recent years as increasing numbers of specialists have adopted its Guidance test, the only test to simultaneously diagnose and guide antibiotic treatment in rapid turnaround time for complex, recurring urinary tract infections.  Studies show that Pathnostics’ proprietary technology has strong potential to reduce hospitalizations and improve patient satisfaction – a significant need and priority across the healthcare industry.  Water Street partnered with Pathnostics in 2019 to leverage our diagnostics expertise and network of resources to expand Pathnostics’ innovative technology and solutions into new therapeutic areas, as well as in current markets.
