Frequently asked questions
Is blood in the urine an emergency?
Heavy bleeding, clots or inability to pass urine need urgent care. Even a single episode of painless blood should be investigated promptly.
Can foods or medicines colour the urine?
Yes — beetroot, some dyes and certain medicines can turn urine red. A urine test confirms whether it is truly blood.
