Significance of Using Fetal DNA in Maternal Plasma for Prenatal Diagnosis of Fetal ABO Blood Types;

Study of Comparing Efficiency of Fetal DNA Extracting from Maternal Cells and Plasma;

Advancement in research on cell-free fetal DNA in urine of pregnant women;

Detection of cell-free fetal DNA in maternal serum for a new prenatal screening marker of Down s syndrome;

Influence of delay in blood-processing on the level of cell-free fetal DNA in maternal plasma sample;

2-hold higher levels of maternal serum cell-free fetal DNA compared with matched controls.

Advancement in Research on Cell-free Fetal DNA in Maternal Plasma;

Results:①Fetal DNA can be detected in maternal plasma as early as at 7-1 th week of gestation; ② And that fetal DNA in maternal plasma reached a mean of 77.

Objective The free fetal DNA in preeeclampsia maternal plasm has been quantitatively assayed by real-time fluorescence quantitative PCR(FQ-PCR) to explore the correlation between the fetal DNA and preeclampsia as well as the assay\'s value in assessment of development and prognosis of preeeclampsia.
