Popis: OBJECTIVE To compare the utility of Gram staining, a urinary antigen detection kit and a sputum antigen detection kit were examined for the rapid and early detection of pneumococcal pneumonia and lower respiratory infectious diseases. METHODS A newly developed sputum pneumococcal antigen detection kit (RAPIRUN), Gram staining, and urinary antigen detection kit (BinaxNOW) were comparatively evaluated for their ability to detect Streptococcus pneumoniae in patients with pneumonia or lower respiratory tract infection. Sputum culture results were used as a standard for comparison. Furthermore, the pneumococcus-positive rates in culture and rapid tests were compared using polymerase chain reaction (PCR) as a reference. RESULTS Of the 169 patients studied, 54 (32.0%) tested positive for S. pneumoniae in culture. S. pneumoniae detection sensitivities for Gram staining, RAPIRUN, and BinaxNOW were 75.9%, 90.7%, and 53.7%, respectively; thus, RAPIRUN had a significantly higher sensitivity than BinaxNOW (p
