The cost of a chorionic villus test to determine fetal chromosomal and genetic disorders is between$2,000 and$3,000. When a woman is pregnant and suspects that her fetus has a chromosomal or genetic disorder, a chorionic villus test is required to assist in the diagnosis. After the placenta has just formed between 10-13 weeks of pregnancy, a puncture needle can be injected into the placenta through the abdominal wall or vagina, and a small amount of chorionic villi can be taken for culture and separation to check for target diseases. It is best to go to a regular hospital for chorionic villus testing and to have the procedure performed by a professional doctor. After the procedure, bed rest and anti-infection medication and fetal preservation medication should be given.
