| Ok well mine isn't even a 4 or have a B or A. Mine are all 3BC or 3CB. One has 95 percent cell survival, two have 90. Then I have a 4BB day 6 blast that only had 80 percent cell survival and my lab said that would be a last choice bc 80 percent cell survival and Day 6 has lower implantation. |
| This is the previous poster, all mine are day6. My 2.5 year of is also a day 6. Once it's PGs Normal thebgrading is out the window, my doctor said. |
| Oh - my clinic said the day 6 slightly lower implantation potential bc they were slow growing. I have a day 6 4BB that only thawed 80 percent but sounds like that's not far off from what you had |
