The number of red blood cells, Hb and color index must be monitored for 1 month 1-2 times a week, and then 2-4 times a month.
Remission is achieved when the number of erythrocytes increases to 4-4.5 million/μl, when the normal size of erythrocytes is reached, aniso- and poikilocytosis disappears, and the number of reticulocytes normalizes after a reticulocyte crisis. After hematological remission is achieved, peripheral blood monitoring is carried out at least once every 4-6 months.
