When to get medical help
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 pee 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 pee 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 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.
