Cerebrospinal Fluid Bacterial Antigen
No Benefit Beyond Gram Stain
Study Methods
May 2010
The bacterial antigen test was performed according to the manufacturer’s instructions. A positive result was indicated by the development of clearly visible agglutination after 3 minutes of mixing. Agglutination of a single test latex without agglutination in the other tests or negative control latexes indicated the presence and identity of the bacterial antigen. Cerebrospinal fluid Gram stains performed after January 2007 utilized a cytocentrifugation step. Prior to that time, cerebrospinal fluid Gram stains had not been subjected to cytocentrifugation.
