My mother's absolute reticulocyte count is > 30,000. But it may take a while yet for her hemoglobin to start rising as a result. The way I understand, levels won't match bone marrow function at first, according to the hematologist. It takes a while, especially with aplastic anemia. She said it's like filling up a gas tank a drip a day.
IST seems to be working. We're not getting too excited yet. With this disease, you never know from day to day.
Health and happiness to everyone!
