The following statement is false regarding Congenital toxoplasmosis ?
The avidity test is helpful to know the time of infection. A high-avidity test result indicates that infection began >16 wk earlier ,which is especially useful in determining time of acquisition of infection in the 1st or final 16 wk of gestation. A low-avidity test result may be present for many months and is not diagnostic of recent acquisition of infection. Reference: Nelson textbook of pediatrics 21 st edition Page 1220
