Clinical Information
Streptococcus pneumoniae is the most frequently encountered bacterial agent of community-acquired pneumonia. Because of the significant morbidity and mortality associated with pneumococcal pneumonia, septicemia, and meningitis, it is important to have diagnostic test methods available that can provide a rapid diagnosis. In instances where empirical antibiotics are provided for community-acquired pneumonia without culture confirmation of S pneumoniae, antigen testing may be useful.
