Anti-Giardia lamblia immunoglobulin G (IgG) is a host-derived antibody produced in response to infection by the protozoan parasite Giardia lamblia, a common cause of gastrointestinal illness known as giardiasis. This IgG antibody targets specific antigens on the surface of the Giardia trophozoites and cysts, contributing to the adaptive immune response by facilitating opsonization and clearance of the pathogen. The presence of Anti-Giardia IgG in serum typically indicates either a past or ongoing infection and is part of the humoral immune profile that develops following exposure to the parasite.
In the research setting, detection of Anti-Giardia lamblia IgG is valuable for studying host-parasite interactions, immunological memory, and the development of long-term immunity. It is also used in seroprevalence studies to assess population exposure to Giardia in endemic areas or specific at-risk populations, such as travelers, children, or immunocompromised individuals. In clinical diagnostics, Anti-Giardia IgG tests—typically enzyme-linked immunosorbent assays (ELISAs)—are employed as an adjunct to stool microscopy or antigen testing, particularly in cases with intermittent cyst shedding or chronic symptoms. While IgG detection alone cannot confirm acute infection, it is helpful when combined with IgM and IgA profiles to provide a more complete picture of infection history and immune response.
