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.
The immunochromatographic test for CSF depends on the presence of a detectable
level of antigen in the CSF, and therefore only supplements culture
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).
