Test Information

​The Streptococcus pneumoniae antigen test has not been evaluated on patients taking antibiotics for greater than 24 hours or on patients who have recently completed an antibiotic regimen.  The effects of over-the-counter drugs have not been determined on persons with pneumococcal meningitis.

Streptococcus pneumoniae vaccine may cause false positive results in urine in the 48 hours following vaccination.  The effect of vaccination has not been determined on persons with pneumococcal meningitis.  Hence, it is recommended that the Streptococcus pneumoniae antigen test should not be performed within 5 days of receiving the S. pneumoniae vaccine.

The accuracy of the Streptococcus pneumoniae antigen test in urine from young children has not been proven.
