Hi Teo,
Remember that your mother still doesn't have any dx! It can be very dangerous to start treatment in her case.
Your mother's bone marrow is producing both RBC and platelets even if they didn't see any precursors in that BMB. She has few cells and it is difficult to understand what is going on in her bone marrow.
I don't know anything about low iron stores and high ferritin as in your mother's case.
Hemo diluted means diluted with blood.
Here is info about the combination of EPO and the growth factor for WBC G-CSF
