Clinical Significance

In the serologic evaluation of congenital syphilis, the transplacental transfer of maternal nontreponemal and treponemal IgG antibodies to the fetus can complicate the interpretation of reactive serologic tests for syphilis in infants. Therefore, treatment decisions frequently must be made on the basis of 1) identification of syphilis in the mother; 2) adequacy of maternal treatment; 3) presence of clinical, laboratory, or radiographic evidence of syphilis in the infant; and 4) comparison of maternal (at delivery) and infant nontreponemal serologic titers using the same test conducted preferably by the same laboratory. All infants born to mothers who have reactive nontreponemal and treponemal test results should be evaluated with a quantitative nontreponemal serologic test (RPR) Refer to CDC STD Treatment Guidelines for comprehensive information.
