ABSTRACT
Objective To evaluate the early diagnostic value of 1,3-β-D glucan(BG) and galactomannan(GM) test for invasive fungal infections(IFI)in intensive care unit(ICU) patients.Methods From 2013 to 2015,the concentration of serum BG and GM were detected in 452 cases of ICU patients,including 182 cases with diagnosis of IFI,46 cases with possible diagnosis of IFI and 224 cases of non-IFI.The diagnostic performance of BG,GM and combined test were analyzed.Results The sensitivity,specificity,positive predictive value(PPV) and negative predictive value(NPV)of BG test were 75.0%,80.4%,75.8%,79.6%.Those of GM test were 25.80%,85.7%,59.5% and 58.7%.The sensitivity and specificity of BG and GM combined test were 87.4% and 94.7% respectively.Conclusion BG and GM combined test could improve the diagnostic efficiency,reduce the false positive rate and false negative rete,which might be helpful for the early diagnosis of IFI in ICU patients.
