Diagnostic value of C-reactive protein and mycoplasma pneumonia antibody in infant respiratory tract infection

Objective:To investigate the diagnostic value of C-reactive protein and mycoplasma pneumonia antibody in infant respiratory tract infection.Methods:1 061 cases of respiratory tract infection in children were detected for mycoplasma prenmoniae antibody.There were 121 cases of positive MP(mycoplasma pueumonia group),50 cases of negative MP(bacterial pueumonia group) and 30 cases of healthy children(control group),and detected CRP in the three groups.Results:There were 286 cases of with positive serum MP in 1 061 infants with respiratory tract infection,the positive rate was 26.96%.There were 35 cases with positive serum CRP in mycoplasma pneumonia,the positive rate was 28.93%,and there were 47 cases with positive serum CRP in bacterial pneumonia,the positive rate was 94.00%,none of positive serum CRP in control group.There was a significant difference in the three groups(P0.01).Conclusion:The incidence of positive serum CRP in mycoplasma pneumonia is significantly higher than that in bacterial pneumonia,the test of MP with CRP is of great value in diagnosing mycoplasma pneumonia and distinguishing it from other pneumonia.
