200 patients (median age 84 years) were included; 133 (67%) had pneumonia. AUROCs for the diagnosis of pneumonia was 0.64 (95% CI 0.56-0.72) for CRP; 0.59 (95% CI 0.51-0.68) for PCT; 0.60 (95% CI 0.52-0.69) for SAA; 0.41 (95% CI 0.32-0.49) for NP; 0.63 (95% CI 0.55-0.71) for CRP/NP; and 0.61 (95% CI 0.53-0.7 for SAA/NP. No cut-off resulted in satisfactory sensitivity or specificity. Accuracy of traditional (CRP, PCT) and newly proposed biomarkers (SAA, NP) and ratios of CRP/NP and SAA/NP was too low to help diagnosing
