Biopsy the placenta: Using an ultrasound to guide the doctor, a small biopsy of the placenta is taken. The biopsy can be obtained using a catheter that is passed through the cervix. The cells of the placenta are then analyzed and the number of chromosomes are counted.

Prenatal diagnosis: During a cvs, a thin needle/catheter is inserted into your placenta. Cells from the placenta are removed and sent to the laboratory. In this way we can check the chromosomes of your developing fetus. Depending on the placenta position and your provider preference this can either be done through the skin of your belly or through your cervix.
