BD Directigen™ Meningitis Test System
The Directigen™ Meningitis Individual Tests are presumptive latex slide agglutination tests for the direct qualitative detection of antigens to H. influenzae type b, S. pneumoniae, N. meningitidis Group B and Escherichia coli K1 in cerebrospinal fluid (CSF), serum or urine. The test can also be used for the direct qualitative detection of antigens to Group B Streptococcus in CSF and serum. In addition, the test kit provides confirmation and serogrouping capabilities from suspected colonies of H. influenzae type b, S. pneumoniae, Group B Streptococcus, and N. menigitidis Group B. Visible agglutination occurs when a sample containing any of these bacterial antigens is reacted with its respective antibody-coated latex beads.
