NABL Cap Accredited    
This test measures the avidity of IgG antibodies against Toxoplasma gondii to help determine whether an infection is recent or long-standing. Low avidity suggests a recent infection, while high avidity indicates past exposure and reduced likelihood of current infection. It is especially useful during pregnancy when accurate timing of infection is essential. Metropolis Healthcare offers precise avidity testing to support clear clinical interpretation
