A 56 year old actress presents to the GP after noticing blood in her urine at times over the last month. She denies any post-menopausal bleeding or post coital bleeding and her last smear test 2 years ago was normal. She is married and denies any vaginal discharge or risk of sexually transmitted infections. There is no dysuria or increased urinary frequency.
Urine dipstick is normal and abdominal and pelvic examinations are unremarkable. A recent NHS health check blood test has revealed her haemoglobin is low at 10.5 and full systems review is otherwise unremarkable. Her observations today are stable and she is feeling well.
What is the most appropriate next step in managing this patient?
