Clinical Significance
IgA, Ab against Toxoplasma gondii have been detected in acute toxoplasmosis, or in uninfected individuals. T.gondii IgA is thus a valuable tool for the early detection of acute disease in pregnant women and individuals with AIDS. Because IgA Ab do not cross the placenta, assessment of IgA Ab against T.gondii is also a reliable method for detecting congenital T. gondii infection.
