Question on blast grade before/after freeze for Ghost/anyone

[aimee613]

Hi all!! I had an FET yesterday of two blasts and before the freeze they were graded 5AA. They both survived the thaw but when I asked for the grade yesterday at the transfer my RE just told me that they looked good. I really wanted to hear the grade so when I questioned the nurse further she just said that they looked beautiful but nobody gave me the post thaw grade. My question is can I assume the grade stayed the same as before the blast? Do the grades change from before to after freeze even if they survive the thaw?

If they were conventionally frozen, then it's almost impossible to grade them after thaw. It's like using a raisin to grade the grape it came from. Most clinics don't bother.

If they were vitrified or cultured awhile after thaw, then it should be relatively straightforward to grade them again. Assuming they survived, the grade should be roughly the same as before.
