Blood in the urine is called hematuria, also known as blood in urine. Under normal circumstances, there are no blood cells in urine. In medicine, after filtering and settling the patient's urine, an optical microscope is used to examine it. If there are more than 5 blood cells in each line of sight, it is called hematuria. If blood cells are only detected under a microscope, but the blood in the urine cannot be seen with the eyes, it is called submicroscopic hematuria; if the eyes can see that the urine is "meat washing water sample" or contains blood, or even blood or blood clots in the urine, it is called naked eye hematuria. Therefore, hematuria is not always detectable by the eyes. You can see blood in the urine with your eyes, and at least 1 ml of blood will seep into 1000 ml of urine. This indicates that the hematuria is more serious and the cause should be found out as soon as possible and active treatment should be initiated.
