A. Dohr et A. Oehme, CRITICAL-EXAMINATION OF AN ENZYME-IMMUNOASSAY FOR DETECTION OF POSITIVE IGM ANTIBODIES AGAINST TOXOPLASMA IN NEWBORNS, Zentralblatt fur Bakteriologie, 278(4), 1993, pp. 566-569
The Toxonostika(R) IgM test, which has been examined in this study, is
a modified antibody capture test (7). Evaluation with sera from newbo
rns 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 ret
ested with another test system.
