0.90-1.09	Equivocal
≥1.10	Antibody Detected

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

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.
