Urinary detection of Streptococcus pneumoniae antigen for diagnosis of pneumonia.
Streptococcus pneumoniae is one of most common causes of community-acquired pneumonia. We evaluated a newly available rapid immunochromatographic test to detect S. pneumoniae in urine samples verifying its importance in the diagnosis of pneumococcal pneumonia. Our data, obtained from 104 patients with community-acquired pneumonia, show that Now S. pneumoniae Urinary Test is characterized by a sensitivity value of 77.7%, a specifity of 98.8%: positive and negative predictive values are 93.3% and 95.5%, respectively. In conclusion, Now S. pneumoniae Urinary Test should be a useful test to establish the etiology of community-acquired pneumonia.
