There are 2 types of PGD — routine PGD and array CGH 24 sure.
routine PGD is a genetic testing procedure – test chromosomes 13, 18 and 21, which are the causes of almost 90% of all genetic-linked abnormalities such as down’s syndrome.
array CGH 24 sure is also a genetic testing done on day 5 by freezing the embryos as it is more detailed testing. It tests all chromosomes.
