Visible Haematuria

What Should I Do If I Have Blood In My Urine?

Your GP will normally investigate blood in the urine as a matter of urgency. Most GPs will perform simple, baseline tests. You may be started on antibiotics to treat a presumed infection. However, if the urine test result comes back showing no evidence of infection, you will normally be referred to your local urology department for more detailed investigations.

Common Facts About Haematuria

  • The most common cause of blood in the urine is cystitis.
  • Blood in the urine, visible or non-visible, should always be investigated.
  • A one-off finding of a small trace of blood in the urine on routine testing may not be significant.
  • Some drugs (e.g. rifampicin, nitrofurantoin) and food (e.g. beetroot) can turn the urine.
