The Typhi Dot (Salmonella Typhi) – IgM test is a serological assay designed to detect IgM antibodies produced by the immune system during the early and acute phase of Salmonella typhi infection.
IgM antibodies usually appear within the first week of illness and indicate a recent or ongoing typhoid infection. This test is particularly useful in patients presenting with prolonged fever, where early diagnosis helps in prompt treatment. Typhi Dot IgM is commonly interpreted alongside Typhi Dot IgG, clinical symptoms, and other investigations such as blood culture.
