Procalcitonin/albumin to urea nitrogen ratio: a novel prognostic indicator for severe fever with thrombocytopenia syndrome

Key Points

• Procalcitonin/albumin to urea nitrogen ratio predicts patient outcomes in severe fever with thrombocytopenia syndrome.
• A higher ratio correlates with increased severity, guiding clinical management.
• Observational analysis across multiple clinical settings assessed this novel biomarker.
• Findings highlight the potential for improved prognostic assessment in SFTS cases.
