摘要：

Objective: To assess the accuracy of a molecular assay for the determination of the fetal RhD status on amniotic fluid (AF) samples. Methods: Amplification of DNA by polymerase chain reaction of a common sequence of the RhD and CE genes and of a unique sequence of the RhD gene was performed on AF directly or after DNA extraction. Samples of AF obtained from patients undergoing amniocentesis for standard obstetric indications were used for the study. Results: Amplification of DNA was successful on 112 of 114 samples. One hundred four fetuses were found to be RhD positive and eight were found to be RhD negative. Serologic confirmation of the RhD blood type was available on 108 samples and DNA diagnosis was correct in all cases. Conclusion: Polymerase chain reaction can be used to determine accurately the fetal RhD blood type from AF samples.
