I am so sorry that the blasts have come that high all of a sudden.
My first bmb the blasts were 5.6%.
9 months later, the bmb showed the blasts at 8.7%, and a few weeks later I had my transplant.
My platelets at that time dropped too, needing platelet transfusions every 10 days.
I hope your karyotype will be good.
