title: Rapid diagnosis of septic arthritis by coagglutination.
abstract: Pneumococcal capsular antigens were detected and serotyped by coagglutination in joint fluids and serum of a patient with septic arthritis within 1 h of obtaining the specimens. Pneumococcal antigens continued to be detected by coagglutination for 3 days, whereas cultures and Gram stains were negative after 1 day of antibiotic therapy.
