Transcervical chorionic villus biopsy

Chorionic villus sampling is an invasive prenatal test performed between 10 and 14 weeks of gestation with the aim of identifying possible genetic alterations or other pathologies in the fetus.

The technique most commonly used to perform this procedure is transvaginal chorionic villus sampling, that is, by introducing the necessary instruments through the vagina and cervix.

A small sample is taken from the villi of the chorion, the tissue that gives rise to the placenta and is derived from the embryo.
