without culture confirmation of Streptococcus pneumoniae, antigen testing may be useful.
Useful For: Rapid diagnosis of pneumococcal pneumonia
Interpretation: A positive result is indicative of pneumococcal pneumonia. A negative result is a
presumptive negative for pneumococcal pneumonia, suggesting no current or recent pneumococcal
infection. Infection due to Streptococcus pneumoniae cannot be ruled out since the antigen present in the
specimen may be below the detection limit of the test. Pneumococcal pneumonia is best diagnosed by
sputum culture.

Clinical Information: Streptococcus pneumoniae causes infectious diseases in children and adults,
including invasive infections (eg, bacteremia and meningitis) and infections of the respiratory tract (eg,
pneumonia and otitis media).(1,2) Streptococcus pneumoniae is responsible for approximately 40,000
deaths and 500,000 cases of pneumonia annually in the United States. There are more than 90 serotypes of
Streptococcus pneumoniae. The serotypes responsible for disease vary with age and geographic location.
