Lulu, they may have procedures like that in the lab - we just don't get to see it.
I recall when going in for EPU, I had my ID checked by the hospital nurses x2, the scientist for the clinic, the anaesthetist and the FS (wasn't always mine) and then I had to sign forms confirming that the sample we handed over was indeed
DH's.
For my first transfer, I had my ID checked by someone before we even entered the transfer room, by the scientist when I got in there... and we had to confirm that it was our name written on the petri dish before they showed us the embryo we were about to transfer.
As time goes on, you become a bit more relaxed about all the checks. I remember one time I was too busy chatting with my FS and it wasn't until afterwards that I recalled I hadn't seen our name on the dish, fortunately
DH was able to confirm that it was indeed there.
I think the issue is that so much of it happens where we can't see it.
