Additional information Suitable for confirmation of reactive RPR, NOT for screening or following response to treatment. For determining whether a Treponemal Antibody-positive neonate has actually been infected transplacentally or whether seropositivity simply reflects IgG antibody from its infected mother, a test for IgM Treponemal Antibody can be obtained at CDC via the Health Dept. Delayed availability of the results of this test, however, precludes their use in deciding to institute treatment.
