Fetal RHD genotype detection from circulating cell-free fetal DNA in maternal plasma in non-sensitized RhD negative women.
OBJECTIVE To examine the performance of the SensiGene Fetal RHD Genotyping Laboratory Developed Test (RHD Genotyping LDT) using circulating cell-free fetal DNA (ccff DNA) extracted from maternal plasma. METHODS ccff DNA was extracted from maternal blood from non-sensitized women with singleton pregnancies in two cohorts, one with a serotype reference (11-13 weeks' gestation) and one with the ...

Objective Maternal-fetal RhD antigen incompatibility causes approximately 50% of clinically significant alloimmunization cases. The routine use of prophylactic anti-D immunoglobulin has dramatically reduced hemolytic disease of the fetus and newborn. Recently, fetal RHD genotyping in RhD negative pregnant women has been suggested for appropriate use of anti-D immunoglobulin antenatal prophylaxi...

risk of HDFN, which can cause fetal anemia, hydrops, and intrauterine fetal death. Babies born with HDFN are at significant risk of neonatal morbidity and mortality [1,2]. Prenatal detection of the fetal RhD status in a pregnant woman with RhD-negative provides useful information for predicting the risk of HDFN and Noninvasive fetal RHD genotyping using cell-free fetal DNA incorporating fetal R...

BACKGROUND This study assessed the diagnostic accuracy of a non-invasive approach to fetal RHD genotyping using cell-free fetal DNA in maternal plasma and a combination of methodological strategies. METHODS Real-time PCR (qPCR) was performed on 216 RhD-negative women between weeks 10+0 and 14+6 of gestation (1st qPCR). qPCR was repeated (2nd qPCR) to increase the amount of each sample for ana...
متن کاملDetection of fetal RHD pseudogene (RHDΨ) and hybrid RHD-CE-Ds from RHD-negative pregnant women with a free DNA fetal kit.
Hemolytic disease of the newborn is a clinical condition in which maternal and paternal Rh blood group antigens are incompatible and the mother is negative for the antigen whereas the father is positive. Analysis of fetal cells recovered from maternal plasma can provide a highly sensitive prenatal diagnosis. The fetal RHD gene in plasma DNA is detected by real-time PCR amplification of two ...
