TUBEX® TF enables diagnosis of acute phase disease by detection of infection-specific Salmonella typhi IgM anti-O9 antibodies in serum. TUBEX® TF is based on Inhibition Magnetic Binding Immunoassay, IMBI® technology — a semiquantitative assay technology utilizing the advantages of the traditional Widal technique, such as simplicity and visual interpretation of fluid. IMBI® technology exhibits specificity normally accorded to ELISAs through the use of purified antigens for detection.
