Additional Information	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).
