Application of prealbumin,C-reactive protein and white blood cell count in infectious diseases

Objective To investigate the relationship and application value of prealbumin(PA),C-reactive protein(CRP) and white blood cell count(WBC) in infectious diseases.Methods PA,CRP and WBC were simultaneously detected in 410 cases of common infectious diseases.The results were statistically analyzed.Results CRP was(37.9 9±50.6)mg/dl and PA was(17.9±3.98)mg/dl in high WBC group.In normal WBC group,CRP was(8.12±11.23)mg/dl and PA was(1.01±3.89)mg/dl.The differences of CRP and PA between the two groups were statistically significant(P0.05).WBC was(19.99±6.32)×109 /L and PA was(17.88± 2.85)mg/dl in high CRP group,while in normal CRP group,WBC was(8.80±4.59)×109 /L and PA was(22.26±3.85)mg/dl.Significant differences of WBC and PA were found between the two groups(P0.05).Linear correlation analysis showed that there was a positive correlation between WBC and CRP,while CRP and PA or WBC and PA were negatively correlated.Conclusion WBC,CRP and PA are valuable in the diagnosis,differential diagnosis as well as treatment evaluation of infectious diseases.However,simultaneous detection of the three parameters is required.
