CVS (Chorionic villous sampling) is a much-known technique that is used to determine any genetic disorder in the fetus. This prenatal testing technique consists of a sampling of chorionic villi which are like finger-like projections of the placental tissue which contain the same genetic material as the fetus. This process is done after 10-12 weeks into the pregnancy.
2 ways samples are collected
- Transabdominal CVS: In this case, a needle is inserted into the abdominal and then observed by ultrasound. This needle doesn’t enter into the amniotic sac and also done under local anesthetic.
- Transcervical CVS: Here, a tube is inserted (catheter) into the placenta through the cervix to get a tissue sample.
When CVS technique is needed
- When you have a sex-linked genetic disease like congenital night blindness, Fragile X syndrome, high blood pressure genes, hemophilia, and many others.
