Blood in the urine can be a sign of kidneys disease or another part of your urinary tract. The medical name for blood in the urine is hematuria. There are two types of hematuria:
- When you can see the blood in your urine, it is called gross hematuria. The urine is pink or red-coloured.
- When you cannot see the blood in your urine without looking at it under a microscope, it is called microscopic hematuria. This will be a finding when the urine is investigated in the laboratory.
