Urine erythrocyte bitemporal test is a laboratory test to determine the source of hematuria (glomerular and non-glomerular origin) by examining the morphology of urinary erythrocytes (normal erythrocytes and deformed erythrocytes). When there are problems with the kidneys or the urinary system, there is a possibility that red blood cells may be present in our urine. By observing the morphology of urinary red blood cells, we can initially determine the source of urinary red blood cells. When the vast majority of urine erythrocyte morphology is normal and regular, non-glomerular origin hematuria is usually considered, possibly due to urinary tract infection, stones, tumors and other factors. Urinary echinococcal erythrocytes have a variable morphology, with 1-3 vesicles protruding from the base of the bagel, and it is a specific marker of hematuria of glomerular origin. Hematuria of glomerular origin is usually seen in all types of glomerular diseases. Clinically, mixed hematuria is common, that is, there are both deformed red blood cells and normal red blood cells under the microscope, and the percentage of deformed red blood cells can be initially used to distinguish between mixed hematuria of glomerular origin and non-glomerular hematuria. Urine erythrocyte phase examination can only be used as a method of initial screening hematuria source, need to be combined with clinical and other examination results, we recommend that patients go to the hospital in a timely manner, and actively cooperate with the doctor to improve the other tests, clear causes, early diagnosis and treatment.
