Comparison of counterimmunoelectrophoresis (CIE), latex agglutination (LA) and staphylococcal coagglutination (COAG) in pneumococcal antigen detection in vitro
Abstract
CIE was compared to agglutination assays employing commercial kits (Directigen, Phadebact), as well as our own LA and COAG reagents, in detection of pneumococcal capsular polysaccharide (PCP) antigens in vitro. Directigen provided the most sensitive assay. CIE was of comparable sensitivity except for PCP antigen types 7 and 14.
