Serum C-reactive protein and blood routine test in diagnosis of pediatric bacterial infectious diseases

Abstract

Objective To investigate the clinical significance of serum C-reactive protein and blood routine test in the diagnosis of pediatric bacterial infections. Methods From January 18, 2017 to December 18, 2018, 114 healthy examinees were selected as a control group, and 114 children suspected with bacterial infections an observation group. Both groups underwent blood routine and serum C-reactive protein tests. Results The NE was (86.54±5.62)%, WBC (12.57±1.65)×109/L, and CRP (35.86±5.45)mg/L in the observation group, which were higher than those in the control group (all P<0.05). The NE was (91.78±6.48)%, WBC (13.83±3.55)×109/L, and CRP (52.86±9.87) mg/L in the children with severe infection, which were higher than those in the children with mild and moderate infection (all P<0.05). The sensitivity of serum C-reactive protein combined with blood routine was 98.96%, the specificity 94.44%, the missed diagnosis rate 1.04%, and the misdiagnosis rate 5.56%. Conclusion In the detection of pediatric bacterial infection, serum C-reactive protein combined with blood routine methods can improve the diagnostic accuracy.
