Streptococcus pneumoniae Antigen, CSF
Also known as: SPN CSF
Use
This test aids in the diagnosis of pneumococcal meningitis by detecting the presence of Streptococcus pneumoniae antigen in the cerebrospinal fluid (CSF). It is used primarily to identify cases of pneumococcal meningitis, a severe infection of the membranes surrounding the brain and spinal cord. This test is particularly useful for patients suspected of having pneumococcal meningitis as it provides a rapid diagnostic tool to confirm the presence of Streptococcus pneumoniae antigens in the central nervous system.
Special Instructions
Not provided.
Limitations
False-positive results may occur due to cross-reactivity with other members of the S. mitis group. Therefore, clinical correlation is recommended to interpret the results accurately. The test should not be used solely as a definitive diagnostic tool without supporting clinical information. Bacterial antigen detection tests performed on CSF should be confirmed with a culture to ensure accurate diagnosis and rule out false positives or negatives.
