Urine red blood cell bitemporal results are interpreted mainly based on the percentage of urinary aberrant red blood cells, and when it is greater than 80%, it is considered to be of glomerular origin. Because there are no red blood cells in normal urine, when the kidney is damaged, red blood cells flow through the damaged glomerular basement membrane into the urine and become extruded and deformed, so the aberration rate is increased. When greater than 80% has clinical significance, but it also depends on the amount of red blood cells in the specific urine. A small amount of red blood cells has no clinical significance, when the red blood cells in the urine are high. Also a red blood cell count greater than 5 under high magnification is clinically significant, considering the presence of urinary tract diseases, such as infections, stones, tumors, etc., depending on the specific situation.
