Abstract

A slide Co-agglutination test for the detection of Salmonella typhi Vi antigen in blood was evaluated for its efficiency in rapid diagnosis of Typhoid fever. The results were compared with conventional methods like Blood culture and Widal test. The test showed a sensitivity of 86.67% and specificity of 88.83% when compared with blood culture positivity or Widal titre above 160. This is a useful rapid diagnostic test for the early diagnosis of Typhoid fever.
