High fluorescence intensity reticulocytes suggests that the bone marrow hematopoiesis is abnormal, which may be caused by anemic diseases, acute blood loss, heavy metal poisoning and other reasons. 1. Anemia: anemia such as iron deficiency anemia, megaloblastic anemia and other anemia, abnormal bone marrow hematopoietic function, high fluorescence intensity reticulocytes can occur. 2. Acute blood loss: acute blood loss in the body causes a decrease in the number of red blood cells in the peripheral blood, and the immature reticulocytes in the bone marrow are released in advance to replenish the reduced red blood cells, and high fluorescence intensity reticulocytes will appear. 3. Heavy metal poisoning: Heavy metal poisoning caused by daily exposure to heavy metals and excessive dietary intake of heavy metals can also lead to high fluorescence intensity reticulocytes. It is recommended that the patient timely consultation, with the doctor to improve the relevant examination, clear cause under the guidance of the physician to carry out targeted treatment, so as not to delay the condition.
