Quick answer
What is Blood in urine?
Blood in the urine (haematuria) can be visible — making the urine pink, red or brown — or invisible, found only when a urine test detects blood (microscopic haematuria). Either way, it is an important symptom that should always be assessed, because although many causes are minor, it can occasionally be a sign of a serious condition.
- How it is treated: Assessment aims to find the cause.
- Self-care: There are no specific self-care measures for blood in the urine itself — the essential step is having it assessed to find the cause.
- When to seek help: See a GP promptly about any blood in the urine — visible or found on a test — even if it is painless or happens only once, so the cause can be found.
What it is
Blood in the urine (haematuria) can be visible — making the urine pink, red or brown — or invisible, found only when a urine test detects blood (microscopic haematuria). Either way, it is an important symptom that should always be assessed, because although many causes are minor, it can occasionally be a sign of a serious condition. Common causes include urine infections, kidney or bladder stones, an enlarged prostate in men, and, in some cases, kidney conditions affecting the filters. Importantly, blood in the urine can also be a warning sign of cancers of the bladder or kidney (and, in men, the prostate), particularly in older people — which is why visible blood in the urine, especially without pain, is taken seriously and investigated promptly. Some causes are harmless or temporary (such as vigorous exercise, or certain foods and medicines that can colour the urine, which is not true blood), but because it is not possible to tell the cause without assessment, any genuine blood in the urine should be checked.
How it is treated
Assessment aims to find the cause. A doctor will ask about the pattern (visible or found on testing, with or without pain, and any other symptoms), examine as needed, and arrange tests — typically a urine test (to check for infection and confirm blood) and blood tests (including kidney function), and, depending on the situation and the person's age and risk, further investigations such as imaging of the kidneys and urinary tract (for example an ultrasound or CT scan) and, particularly for visible haematuria or higher-risk cases, a camera examination of the bladder (cystoscopy). Because visible blood in the urine can indicate cancer, it is often investigated via an urgent referral pathway to exclude or catch this early, even though many cases turn out to have a benign cause. Treatment then depends entirely on the cause — for example treating an infection, managing stones, treating an enlarged prostate, managing a kidney condition, or treating a cancer if found. Where investigations find no serious cause, this is reassuring. The key message is that any blood in the urine should always be checked, as finding a serious cause early greatly improves outcomes, while many causes are minor and treatable.

When to get help
When to see a doctor
See a GP promptly about any blood in the urine — visible or found on a test — even if it is painless or happens only once, so the cause can be found. Visible blood in the urine is investigated promptly, as, although many causes are minor, it can occasionally be a sign of cancer, which is best caught early.

Answers
Blood in urine: frequently asked questions
Should blood in the urine always be checked?
Yes — whether visible or found on a urine test, and even if painless or a one-off, blood in the urine should always be assessed. Many causes are minor and treatable, but it can occasionally signal a serious condition, including cancer, which is best caught early.
What causes blood in the urine?
Common causes include urine infections, kidney or bladder stones, and an enlarged prostate in men. It can also relate to kidney conditions, and, importantly, can be a warning sign of bladder, kidney or prostate cancer, particularly in older people — which is why it is investigated.
