Abstract:
Objective To explore the diagnostic values of procalcitonin(PCT),C-reactive protein (CRP),white blood cell(WBC),and neutrophil(N%)in bacterial infectious diseases. Methods Selected 272 patients with bacterial infectious diseases as the research object,all the patients were in accordance with diagnostic criteria of infection,and confirmed by laboratory examination and microbial cultures. Results The total sensitivity of bacterial infection was PCT > CRP > N% > WBC,and the specificity was PCT > CRP > WBC > N%. After different bacterial infection,klebsiella pneumonia was larger in view of PCT sensitivity than escherichia coli, followed by staphylococcus aureus,streptococcus pneumonia,and bauman acinetobacter in ranking. In view of CRP sensitivity,streptococcus pneumonia was larger than klebsiella pneumonia,followed by escherichia coli, staphylococcus aureus,and bauman acinetobacter in ranking. In respect of WBC sensitiveness,bauman acineto-bacter was larger than escherichia coli,followed by staphylococcus aureus,streptococcus pneumonia and klebsiella pneumoniae.In respect of N% sensitivity,streptococcus pneumonia was larger than klebsiella pneumonia,followed by bowman acinetobacter,escherichia coli,and staphylococcus aureus in ranking.After bacterial infection,PCT, CRP,WBC and N% were significantly higher than normal control group,and significantly higher than normal refer-ence value. After different bacterial infections,in view of the PCT level,klebsiella pneumonia was higher than streptococcus pneumonia,followed byescherichia coli,staphylococcus aureus,and bauman acinetobacter in rank-ing.In view of CRP level,klebsiella pneumonia was higher than streptococcus pneumonia,followed by escherichia coli,staphylococcal aureus and bowman acinetobacter. In view of WBC level,staphylococcus aureus was higher than bowman acinetobacter,followed by escherichia coli,klebsiella pneumonia and streptococcus pneumoniae. In view of N% level,klebsiella pneumonia was higher than streptococcus pneumonia,followed by bowman acineto-bacter,staphylococcus aureus and escherichia coli. Conclusion In terms of the sensitivity of PCT,CRP,WBC and NEC% to bacterial infection,the sequence is PCT>CRP>N%>WBC.
