Blood in urine

Blood in urine (pee) is not usually caused by anything serious but you must get it checked out by a GP.


Ask for an urgent GP appointment or call 111 if

you have blood in your urine and:

  • you do not have any other symptoms
  • it's the first time it's happened
  • there's only a small amount of blood
  • you're not sure it's blood

Blood in your pee may be bright pink, red or dark brown.


Blood in your pee could come from anywhere in the urinary tract – the bladder, kidneys or urethra (the tube that carries pee out of the body).

If you have other symptoms, this might give you an idea of the cause. Do not self-diagnose – see a GP if you think it's blood in your pee.
