A high percentage of hyperfluorescent intensity cells is often indicative of high proliferation of red blood cells in the bone marrow. During routine blood tests, a high percentage of hyperfluorescent intensity cells often indicates a high percentage of reticulocytes in the patient’s blood. Reticulocytes are the immature stage of red blood cells, which can reflect the hematopoietic function of bone marrow, and a high percentage of reticulocytes often suggests that the patient’s bone marrow red blood cells are proliferating more vigorously. Often diseases such as nutritional anemia, hemolytic anemia, and anemia caused by excessive blood loss can lead to a high percentage of reticulocytes, resulting in a high percentage of hyperfluorescent cells on examination. When the test found that the high fluorescence intensity cell percentage is high, the patient needs to identify the specific cause of the disease, and then under the guidance of the doctor to carry out targeted treatment.
