@LF82 I haven't had PGT-A testing yet but I have read quite a lot about it and it's a tricky one.
As far as I understand it, there are 3 possible results: all cells normal, all cells abnormal, a mixture of normal and abnormal. As I also understand it, abnormal cells can and do self-correct. Only a small sample of cells from the embryo are tested so it can only tell you what those cells look like. Apparently Robert Winston's clinic developed it and it was originally used for people with specific genetic conditions, to stop them passing them on. It wasn't intended to be used in a more general way.
I think it can be useful if you have lots of embryos, or if you've had more than one miscarriage. It's expensive so if you only get one or two embryos, in my opinion the extra cost isn't worth it - you may as well just transfer the embryos and hope for the best. But if you had, say, 10 embryos and a history of miscarriage, I would probably do it, to reduce the risk of further miscarriages by selecting only the 'normal' ones for transfer.
I believe in the UK, any embryos classed as abnormal after PGT-A testing have to be destroyed.
Sending love and good thoughts for your eggs. Have a nice rest this afternoon. Xx
@Jx3303 Lots of love to you too. So exciting that all's moving forward for your transfer. Xx
