|Explanation=Explanation: All infants born to mothers who have reactive non-treponemal and treponemal test results should be evaluated with a quantitative non-treponemal serologic test (RPR or VDRL) performed on infant serum, because umbilical cord blood can become contaminated with maternal blood and yield a false-positive result. Conducting a treponemal test (i.e., TP-PA, FTA-ABS, EIA, or chemiluminescence assay) on a newborn’s serum is not necessary. | |Explanation=Explanation: All infants born to mothers who have reactive non-treponemal and treponemal test results should be evaluated with a quantitative non-treponemal serologic test (RPR or VDRL) performed on infant serum, because umbilical cord blood can become contaminated with maternal blood and yield a false-positive result.
