Blood in urine can be:

  • Macroscopic which means blood can be seen in urine without needing tests or special equipment 
  • Microscopic which means blood can only be found through testing the urine 

Blood in urine can be found for many reasons. This could be from exercise, periods, injury or other causes.

The doctor will check for any serious causes such as infection, inflammation or cancer. They may have a closer physical check and do more tests.

The risk of cancer being the cause of macroscopic haematuria is higher with smoking, chronic bladder infections, increasing age and medication history.
