Aid in the diagnosis of pneumococcal meningitis.
Within 24 hours
Transfer 1 mL CSF to an ARUP Standard Transport Tube. (Min: 0.5 mL)
Refrigerated or frozen.
Specimen types other than CSF.
Stability: Ambient: 24 hours; Refrigerated: 1 week; Frozen: 1 week
False-positives may occur because of cross-reactivity with other members of S. mitis group. Clinical correlation is recommended.
Patients who have received the S. pneumoniae vaccines may test positive in the 48 hours following vaccination. Avoid antigen detection testing for at least 5 days after receiving vaccination.
The College of American Pathologists (CAP) requires that bacterial antigen detection testing performed on CSF specimens be confirmed by culture (CAP MIC.22550). When S. pneumoniae antigen detection on CSF specimens is ordered by the University of Utah Hospital, Huntsman Cancer Hospital, or the VA Hospital of Salt Lake City, a CSF culture will be added automatically (see 0060106 for submission requirements). All other CSF specimens will be processed with the assumption that a culture was performed before sending to ARUP unless a specific request for culture is included with the test order.
