Various biomarkers believed to be useful in diagnosing sepsis have been reported; in the Sepsis‐2 (2003),8 leukocyte count (>12,000/μL or <4,000/μL or >10% immature forms), c‐reactive protein level (CRP, >reference value + 2 standard deviation (SD)), and procalcitonin level (PCT, >reference value + 2 SD) were listed as inflammatory biomarkers. Here, CRP is linked to Sepsis.
