Meticulous antenatal screening for maternal syphilis can prevent congenital syphilis. In the event of inadequate antenatal screening, determination of reagin reactivity on cord blood becomes mandatory. A card test utilising the VDR carbon antigen (Wellcome) was used to screen cord blood samples for reagin reactivity. The same blood was also screened by a reference laboratory, where the VDRL card test was repeated and every result was substantiated by treponemal tests. The VDRL card test done at the local laboratory had a sensitivity of 83,3% and a specificity of 99,8% when compared with the results of the reference laboratory.
