Doctor's answer:

Hello, normal urine contains a very small amount of red blood cells. Uncentrifuged urine under a microscope can have 0 to 2 red blood cells per high-power field. If the number exceeds this, it is considered hematuria. There are many causes of hematuria, but it is mainly caused by urinary system diseases, such as renal tuberculosis, nephritis, urinary tract infection, urinary tract stones, and urinary tract tumors.
