Hi Edbol,
You know patients with serum EPO that is more than 500 often don´t have a good repsonse at Aranesp and similar drugs. Serum EPO is made by the kidneys that try to push the bone marrow to make more red blood cells.
You have to ask the doctor for your husbands serum EPO - the doctor should have taken that test initially because otherwise he/she won´t know if your husband should have Aranesp and similar drugs.
You can look at page 15 in this handbook for MDS:
