CRP and Sepsis: In a 2019 meta-analysis of 14 studies and 2,471 patients [43], CD64 bettered CRP and PCT for diagnosing sepsis, as the area under the summary receiver operating characteristic (SROC) curve was larger for neutrophil CD64 than for CRP (0.89 (95% CI 0.87–0.92) vs. 0.84 (95% CI 0.80–0.88), p < 0.05) or PCT (0.89 (95% CI 0.84–0.95) vs. 0.84 (95% CI 0.79–0.89), p < 0.05).
