If the human body has abnormal hemoglobin, there may be various symptoms. For example, when the hemoglobin increases, there may be thrombosis, and the blood viscosity increases. When the hemoglobin decreases, the oxygen-carrying capacity will decrease. Therefore, if a blood system disease or other system disease affects the hematopoietic system, it is necessary to check the hemoglobin.
