NCT00871195

Brief Summary

The objective of this study is to evaluate the performance of Sequenom's noninvasive test for fetal RHD genotype. The test uses MALDI-TOF mass spectrometry to detect DNA. The study is specifically designed to determine whether RHD typing using free fetal DNA in maternal circulation can accurately predict the neonatal RhD phenotype at birth.
