What happens to abnormal urine red blood cells

Urinalysis may sometimes indicate an increase in red blood cells in the urine, which may not be visible to the naked eye, because more than 1ml of blood per 1000ml of urine will appear as macroscopic hematuria. If the amount of bleeding is very small, it will appear under the microscope. More than or equal to 3 red blood cells per high power microscope is called microscopic hematuria. Any hematuria has a cause, and hematuria should be ruled out, especially in older patients. Urinary tumors should be ruled out. Therefore, microscopic hematuria is a very important signal in laboratory tests. It is necessary to see a doctor in time for systematic examination and laboratory tests to find out the cause and make a clear diagnosis.
