Background
Serum biomarker that may help distinguish between bacterial infection and other causes of infection or inflammation.
Use
Differentiate lower respiratory inflammation/infection into bacterial vs. other etiology, and help clinicians choose if antibiotics are appropriate.
Evidence
- In patients with lower respiratory tract infections, procalcitonin guided antibiotic stewardship didn't result in worse outcomes, but did reduce antibiotic exposure and their associated effects [1]
- Procalcitonin-guided approach to inform antibiotic therapy didn't result in decreased antibiotic use compared to usual care [2]
