cfDNA Fetal RBC Genotyping in Alloimmunized Pregnancies: July 2024 NEW DATA

In September 2022, a cell-free DNA assay using next-generation sequencing and quantitative counting tech for fetal antigen status determination became clinically available in the USA. This allowed maternal screening for fetal RBC genotypes for RH negative patients. This test was recognized by thre ACOG in March 2024 as one option to “triage” anti-D immunoglobulin in RH negative women. But can this technology be trusted in alloimmunized patients? In women with antibodies against foreign antibodies, this cell free DNA fetal screening option MUST get it right. We now have that data. In this episode, we will summarize remarkable results, published ahead of print on July 25, 2024 in the Green Journal. This study is a win for science and prenatal care.
