Hi Lovely, Thanks for writing in. Pre implantation genetic diagnosis of thalassemia. This procedure involves many steps: a. In vitro fertilization is used to create a zygote which is then nurtured into an embryo. This is done for multiple empbryos b. Then each of these embryos is tested for thalassemia prior to the selection of embryos for transfer to the uterus to establish pregnancy You can go this website to find out where PGD is done in India http://www.selectsurrogacyindia.com/genetics/PGD_preimplantation_genetic_diagnosis_india.html Hope this helps
