Clinical evidence supporting host response testing for infection diagnosis

This clinical evidence overview summarizes multiple studies evaluating the performance and clinical utility of MeMed BV, a host response assay designed to distinguish between bacterial and viral infections. Across more than 20,000 patients and multiple international studies, the assay consistently demonstrates high diagnostic accuracy, outperforming traditional biomarkers such as CRP and procalcitonin. Clinical trials and real‑world studies show that MeMed BV can reduce unnecessary antibiotic use, support decision-making in emergency and urgent care settings, and improve patient management without increasing adverse outcomes. These findings highlight the potential of host response diagnostics to address diagnostic uncertainty and improve antibiotic stewardship.
