Study on the Differential Value of Serum CRP,PCT and Routine Blood Tests in Bacterial Infectious Diseases in Children
Objective To study the value of serum CRP(C-reactive protein),PCT(procalcitonin),and routine WBC(white blood cell count)combined for testing bacterial infectious diseases in children.Methods The clinical data of 43 cases of children with bacterial infections diagnosed in Shanxian Dongda Hospital from January 2021 to December 2023 werere retrospectively selected as the observation group,and the clinical data of 43 healthy children who under-went physical examination in the hospital during the same period were retrospectively selected as the control group.The results of the serum CRP,PCT and blood routine WBC indexes were compared,and the sensitivity,specificity and accuracy of the single-indicator and three-indicator combined tests were calculated.Results The levels of CRP,PCT and blood routine WBC indexes of infected children in the observation group were significantly higher than those of the control group,and the differences were statistically significant(all P<0.05).The sensitivity 95.35%and the accu-racy 94.19%of the three-indicator combined test of the disease were significantly higher than that of the single-indicator test,and the differences were statistically significant(both P<0.05).Conclusion Clinical differential diagno-sis of children's bacterial infections can be made by combining the three tests of CRP,PCT,and routine blood WBC indexes,which is more accurate than the single-indicator analysis,and provides data support for subsequent treat-ment.
