How should I Collect Mid Stream Urine (MSU)?

  • Do not empty your bladder for three hours, if possible.
  • Label the container with your surname, first name, date of birth, date/ time and referring doctor.
  • Wash your hands, and then wash your genital area with water.
  • The aim is to get a sample of urine from the middle of your bladder.
  • Urine is normally sterile (no bacteria present). If bacteria are found in the sample, it means that the urine may be infected.
  • A 'mid-stream' sample is the best sample as the first bit of urine that you pass may be contaminated with bacteria from the skin.
  • Women - hold open your labia (entrance to the vagina) apart while urine is passed. If you have a vaginal discharge or period, a tampon should be inserted prior to collecting the sample.
  • Men - Uncircumcised males should retract the foreskin while the urine is passed. Do not open the sterile bottle until you are ready to take the sample.
  • Pass some urine into the toilet. Without stopping the flow of urine, catch some urine in the sterile bottle (fill approximately half full). (The bottle will be provided by the phlebotomy Reception). Finish off passing urine into the toilet. Close the lid firmly.
  • Wash hands thoroughly with soap and water.
  • Check that the form contains the full name, address and date of birth of the person sampled and add the date and time the sample was collected.
  • The sample should ideally be brought to the lab within one hour.
  • If that is not possible, put the sample in the fridge until it is brought to the lab.
