The Typhi Dot (Salmonella Typhi) – IgG test is a serological assay used to detect IgG antibodies produced by the immune system in response to Salmonella typhi infection.
IgG antibodies usually appear later in the course of infection or after recovery and may persist for a long time. A positive IgG result suggests past exposure, late-stage infection, or previous typhoid fever, rather than an acute illness. This test is often interpreted along with Typhi Dot IgM, clinical symptoms, and other investigations such as blood culture to understand the stage of infection.
