Procalcitonin (PCT) serves as a robust biomarker for diagnosing bacterial infections, offering high sensitivity and specificity. Serum PCT levels rise rapidly during severe systemic bacterial infections and return to baseline faster than CRP once the infection is controlled. However, localized infections typically do not induce significant PCT elevations. Consequently, PCT is widely utilized for the diagnosis and differential diagnosis of sepsis, as well as evaluating its severity and clinical progression.
