title: Serum hCG assay: a method for detection of contamination of fetal blood samples.
abstract: Serum human chorionic gonadotrophin (hCG) can be assayed in specimens obtained by percutaneous fetal blood sampling to check for the absence of maternal blood or amniotic fluid contamination. In order to assess the accuracy of this approach, we measured serum hCG in 44 pure fetal blood samples obtained by intracardiac puncture. The mean fetal serum hCG concentration was 52 IU/l, and the ratio of maternal to fetal serum hCG concentration never exceeded 1.1 per cent, which represents the smallest contamination rate detectable by this method.
