title: Critical examination of an enzyme immunoassay for detection of positive IgM antibodies against toxoplasma in newborns.
abstract: The Toxonostika IgM test, which has been examined in this study, is a modified antibody capture test (7). Evaluation with sera from newborns revealed that, like in the ELISA tested in 1988, doubtful or false positive results were obtained in 10% of the cases (6). Therefore, a positive toxoplasmosis IgM result in newborn sera should always be retested with another test system.
