Learn more about blood in the urine for women: overview
Blood in urine (pee) isn't usually caused by anything serious but you must get it checked out by a GP.
See a GP if you notice blood in your urine, even if:
- you don't have any other symptoms
- it's only happened once
- there's only a small amount of blood
- you're not sure it's blood
Blood in your urine may be bright pink, red or dark brown.
Blood in urine must be checked out because it can be a sign of cancer. This is easier to treat if it's found early.
What happens at your appointment
The GP will ask about your symptoms and may need to examine your bottom (rectum), or vagina if you're a woman.
They might also:
- ask for a urine sample or arrange a blood test
- prescribe antibiotics if they think you have an infection
- refer you to a specialist for tests
Causes of blood in urine
Blood in your urine 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. Don't self-diagnose – see a GP if you think it's blood in your urine.
