The Typhi Dot IgM, IgG test is a rapid serological test used to detect antibodies against Salmonella typhi, the bacteria responsible for typhoid fever. This test helps determine whether a person has an active or past infection. The IgM antibody indicates a recent or current infection, while the IgG antibody suggests a past infection or immunity due to previous exposure. The test is particularly useful for early diagnosis, as it provides quicker results compared to traditional Widal tests or blood cultures.
A positive IgM result suggests an active typhoid infection, while a positive IgG result may indicate past infection or immunity. Further tests, such as blood culture, may be needed for confirmation.
