Streptococcus pneumoniae Antigen, Random, Urine
Use
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. This test is useful for the rapid diagnosis of pneumococcal pneumonia.
Special Instructions
Not provided.
Limitations
A negative result does not exclude Streptococcus pneumoniae infection. A diagnosis of S pneumoniae infection must take into consideration all test results, culture results, and the clinical presentation of the patient. S pneumoniae vaccine may cause false-positive results, especially in patients who have received the vaccine 5 days prior to specimen collection. This assay has not been validated for use with body fluids other than urine or cerebrospinal fluid. The performance of this assay in patients who have received antibiotics for more than 24 hours has not been established. The accuracy of this assay has not been proven in small children.

Collection Instructions
1. Collect a random urine specimen. 2. No preservative. 3. Excessively bloody or very turbid specimens containing protein, cells, or particulates will be canceled, as they can inhibit the function of the test. 4. Do not centrifuge to remove particulates. 5.
