Comparative efficacy of indirect haemagglutination test, indirect fluorescent antibody test and enzyme linked immunosorbent assay in serodiagnosis of typhoid fever.
In the present study three tests, viz. IHA, IFA and ELISA were compared for their sensitivity, specificity and predictive values in serodiagnosis of typhoid fever. One hundred and eleven sera samples comprising 41 culturally confirmed, 14 clinically suspected and 56 normal controls were tested. Among the three tests, ELISA was found to be the method of choice using single serum sample.
