Typhi Dot IgM

Typhi Dot IgM test is done to detect IgM antibodies against Salmonella typhi, the bacteria that causes typhoid fever. Typhoid mainly spreads through contaminated food and water and manifests in the form of fever, loss of appetite, stomach pain, and diarrhea.
As this test is not quantitative, it only detects the presence or absence of Salmonella typhi. Widal test is advised in case titers of specific antibodies (IgM and IgG ) are required.
