High red blood cell high magnification mainly refers to the fact that more red blood cells can be seen under the microscope, and red blood cells mainly represent the presence of blood. For neurosurgical diseases, the most common ones mainly include: 1. urinary tract injury, which can be reflected by urine routine with high urine red blood cell index. 2. ventricular hemorrhage, patients who undergo external drainage because of ventricular hemorrhage, cerebrospinal fluid laboratory tests suggest high red blood cells in cerebrospinal fluid routine. Both of these causes can lead to high erythrocyte high-powered visualization. For this condition where abnormalities occur, symptoms are usually effectively relieved and controlled through active treatment.
