High fluorescence intensity reticulocyte ratio is due to the strong hematopoietic function of bone marrow. 1. Red blood cells that are not fully mature are called reticulocytes, which can be used to reflect the hematopoietic function of the bone marrow red lineage, and are important for the judgment and treatment of hematological diseases. 2. High fluorescence intensity reticulocyte ratio is due to the bone marrow hematopoietic function, the emergence of proliferative anemia, such as iron deficiency anemia, megaloblastic anemia, hemolytic anemia, hemorrhagic anemia. 3. In addition, the ratio of high fluorescence intensity reticulocytes will be increased in patients with proliferative anemia after taking vitamin B12, iron and folic acid treatment. When the patients have high fluorescence intensity reticulocyte ratio, they should go to the hospital in time for further examination of blood routine, ferritin, bone marrow aspiration, liver function, etc., to clarify the cause of the disease and take symptomatic treatment under the guidance of the doctor.
