In order to prove the presence of bacterial infection, serum biomarkers like procalcitonin (PCT) are considered useful. Biochemically, PCT is the prohormone of the hormone calcitonin, released into the circulation in response to bacterial infection. PCT is the best-studied sepsis biomarker for clinical use. Among all sepsis markers, only PCT has achieved universal use throughout developed countries in the last decade.
