Can high betas sometimes point to down syndrome? I have read its possible. We used a donor and of 20 eggs retrieved, only 5 made embryos and of those 5 only 1 tested PGS normal which we recently used. I have read PGS can miss down syndrome though.
now my first beta, 10 days post Frozen embryo transfer, was at 617. Second one 48 hours later was 1360. In the back of my mind I am slightly concerned about Down syndrome since I have read that can cause very high betas and because 19 of 20 eggs were already not good.
