A comparative study of blood culture, widal test and immunochromatographic assay for rapid diagnosis of typhoid fever in a tertiary care centre

Typhoid fever continues to be a major public health problem and the emergence of antimicrobial resistance by Salmonellae typhi adds to the complexity in treating the patients. Salmonella enterica subspecies enterica serovar typhi, the human specific, causative agent of typhoid fever, is one of the most common infectious diseases in developing countries like India 1. Widal test is associated with numerous limitations, but is still considered and extensively used as the diagnostic tool in our area. The bacteriological identification by blood culture is the best confirmative test of Typhoid fever. The aim of the study was to determine the reliability of Immunochromatographic test for the early diagnosis of typhoid fever when compared to the Widal test. The present study was carried out in Tirunelveli Medical College and Hospital, Tirunelveli for a period of one year from June 2017 to July 2018. | A comparative study of blood culture, widal test and immunochromatographic assay for rapid diagnosis of typhoid fever in a tertiary care centre
