A clinical study presented by Antoine Dewitte at the Sepsis Update Congress 2025 highlights a culture-free blood test that significantly improves the detection of bloodstream infections in suspected sepsis patients. The assay, which delivers results in approximately five hours, outperforms traditional blood cultures, detecting nearly three times as many infections. Its innovative method enriches intact bacterial cells for rapid genomic identification, reducing reliance on culture growth while facilitating early clinical decision-making and potential shifts in sepsis management practices.
