1 mL urine OR 1 mL CSF* (please see Remaks)
Immunochromatographic test for S. pneumoniae antigen. Urine antigen test for S. pneumoniae pneumonia. CSF antigen test for S. peumoniae meningitis.
Positive for pneumococcal antigen; Negative for pneumococcal antigen. Infection due to S. peumoniae cannot be ruled out since the antigen present in the sample may be below the detection limit of the test.
4 - 24 hours
The immunochromatographic test for CSF depends on the presence of a detectable level of antigen in the CSF, and therefore only supplements culture procedures. It is a laboratory requirement that a CSF bacterial culture be done every time antigen detection test is ordered. Please ensure that a CSF culture order is placed concurrently with a CSF antigen detection order, and that sufficient CSF sample is provided for both tests (at least 2 mL CSF in total).
