Over 20 years have passed and, while earlier PGD tests were problematic, marked improvements have been made in the methodology, with better outcomes. Currently, the most popular technique is CCS, which tests all 23 pairs of chromosomes. In fact, the name PGD is often replaced with comprehensive chromosomal screening (CCS). With the availability of preimplantation screening, many patients prefer embryo screening over amniocentesis or intrapartum screening, avoiding the possibility of a difficult decision or a second trimester termination in the event of an abnormality.
