Uroflow Test

What is a uroflow test?

  • A urine flow test is done to find out the amount of urine you pass and the rate at which you empty your bladder.
  • You will be asked to pass urine into a container, and a graph will be printed out, showing the amount of urine passed and the flow of urine.
