Order Name:
Streptococcus pneumoniae Antigen (Urine)

 
 
Clinical Information:
Streptococcus pneumoniae is the most frequently encountered bacterial agent of community-acquired pneumonia (CAP). 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 CAP without culture confirmation of Streptococcus pneumoniae, antigen testing may be useful.
 
Reference Value:
Negative
 
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. A negative result does not exclude Streptococcus pneumoniae infection. A diagnosis of Streptococcus pneumoniae infection must take into consideration all test results, culture results, and the clinical presentation of the patient. Streptococcus pneumoniae vaccine may cause false-positive results, especially in patients who have received the vaccine within 5 days of having the test performed.
