Abstract
Objective To evaluate the clinical diagnostic value of procalcitonin (PCT),C-reactive protein (CRP) on bacterial pneumonia.Methods The difference of PCT and CRP concentration in serum of patients who were infected with virus,bacteria and mycoplasma was analyzed.Results There was statistical significance on CRP,PCT,WBC,NEUT among above-mentioned patients (P ＜0.05).The concentration of CRP increased at maximum in patients infected with bacteria,secondly in patients infected with mycoplasma.The PCT concentration increased at maximum in patients infected with bacteria,did not change in patients infected with virus or mycoplasm.There was statistical significance on CRP,PCT,WBC among different severity patients infected with bacteria (P ＜0.05).Conclusions PCT and CRP have a good clinical diagnostic value on pathogen diagnosis,disease severity and prognosis assessment of bacterial pneumonia.
