The Collection of a random urine sample

Information for patients from the Department of Pathology

Your GP or another healthcare professional has asked you to collect a urine (pee) sample. This leaflet will explain the following.

We hope this leaflet answers some of the questions you may have. If you have any further questions or concerns, please speak to a member of your healthcare team.

Why do I have to collect this sample?

The sample will help your doctor diagnose a health condition or rule one out. This may be to:

If your urine contains anything unusual, you may have an underlying health problem.

What should I do before I collect my sample?

Before collecting your sample, please read and follow all the instructions you have been given.

Your doctor or nurse will give you a sterile container for your sample. If your doctor or nurse has not already filled in the label, please make sure you complete the label with a biro. Add your:

  • first name

  • surname, and

  • date of birth.

  • If you know your NHS number, please also write this on the container.

If you are given a sample container for Microbiology testing with a red top (see photo) you will also be given a small, disposable cup. This cup is used to catch your urine and then transfer it to the red-top tube.

What is the powder already in the container?

White-top containers do not contain any powder.

Red-top containers contain a small amount of boric acid powder - do not discard. The boric acid is important and makes sure that the urine is suitable for testing for bacteria. Avoid skin contact and do not eat. Keep the container out of the reach of children.

How do I collect my sample?

Your doctor will often ask you to collect an early morning sample, although urine collected at other times of day is acceptable for some tests. An early morning sample is the first sample you pass after waking in the morning. It is the urine that has collected in your bladder overnight.

Unless told otherwise by your doctor, please follow the steps below.

What do I do with the sample when I have finished?

Please follow these instructions carefully. Failure to do so will make it difficult for your doctor to interpret the results. You may have to do the test again.

Who do I tell if I have a problem?

New specimen containers are available from:

Please discuss any sample collection problems with your healthcare professional.

How will I find out my results?

The laboratory will send the results of your test back to the doctor who requested the test. Most results will be available within 1 week, but some take up to 6 weeks.

Where can I get further information?
