I can’t speak for other PGT companies, but I know Herasight will do genetic testing on multiple prospective egg or sperm donors for clients.
I don’t know of a single egg or sperm bank that does this kind of in depth testing by default. They don’t even offer basic polygenic scores, let alone expanded carrier screening.
You can’t screen egg directly because there’s no way to read the genome without destroying it, and eggs only have one copy.
You could in theory reconstruct the donor’s genome if you had enough of her eggs, but that would require buying and fertilizing a bunch of them.
It’s easiest to just directly ask the donor to get genetically sequenced.
