Evaluation of the BinaxNOW registered Streptococcus pneumoniae antigen test on fresh, frozen and concentrated urine samples in elderly patients with and without community-acquired pneumonia

We evaluated the BinaxNOW registered urine antigen test in elderly. For fresh un-concentrated urine samples, the sensitivity for pneumococcal pneumonia was 63% and specificity 97%. After freezing and concentration, the results comparable to positive control line in intensity at 60min gave high sensi...

Description
Summary:We evaluated the BinaxNOW registered urine antigen test in elderly. For fresh un-concentrated urine samples, the sensitivity for pneumococcal pneumonia was 63% and specificity 97%. After freezing and concentration, the results comparable to positive control line in intensity at 60min gave high sensitivity (81%) with no loss in specificity (96%).
