Toxoplasma gondii specific IgG avidity assay: Role and implication in the confirmatory diagnosis of acute toxoplasmosis in seropositive pregnant women (original) (raw)

Toxoplasma gondii is a protozoan parasite that poses serious risks to fetuses during pregnancy when a mother is infected. Diagnosing acute infection is particularly challenging as many women show no symptoms or have misleading serological markers. This study evaluates the effectiveness of the IgG avidity test to differentiate between acute and past T. gondii infections in seropositive pregnant women. It was found that the test accurately indicated the risk of congenital transmission, thereby influencing clinical decisions and improving patient management.
