Overview
Urine tests are common before many medical procedures. These tips help you provide a clean, accurate sample so your healthcare team can check your health quickly and safely.
Key facts
- A clean catch urine sample means you collect midstream, not the first or last part of your urine.
- Drinking enough water before the test makes it easier to urinate and gives a better sample.
- Avoid eating or drinking anything that might color your urine, like beets or certain vitamins, unless your doctor tells you otherwise.
Yes. Many procedures, including surgeries, scans, and routine check-ups, require a urine sample to check for infections, kidney function, or other health issues.

When to see a doctor
See a doctor urgently if:
- You cannot urinate at all and it has been more than 6 hours
- You see blood in your urine (bright red or dark) and are in pain
- You have a fever along with burning or pain when urinating
Book a routine appointment if:
- You have questions about how to collect a clean sample
- You are not sure if a medicine you take affects your urine test
- You need another urine test because your sample was contaminated
Diagnosis
A urine test is done by collecting a sample of your urine in a sterile cup. The sample is then sent to a lab to look for signs of infection, blood, protein, or other substances.
Tests that may be done
- Clean catch urine sample (midstream collection)
- Urine dipstick test (a quick strip test done at the bedside)
- Urine culture (grows bacteria to check for infection)
What to expect at your appointment
You will be given a clean, dry cup and sometimes an antiseptic wipe. You go to a private restroom, clean your genital area, start urinating, then catch a small amount in the cup. Finish urinating into the toilet. Then close the cup and hand it to a staff member. The whole process usually takes just a few minutes.
Treatment
If your urine test shows a problem, your healthcare team will discuss the next steps with you. This may include more tests, medicines, or changes to your procedure plan.
Self-care at home
- Drink plenty of water in the hours before your test (unless your doctor says otherwise)
- Avoid foods or drinks that can change urine color, like carrots, beets, or coffee, before the test
- Try to relax – taking a few deep breaths can help when you are nervous
Medical treatments
If an infection is found, your doctor may prescribe antibiotics or other treatments. If kidney problems show up, you may need more specific tests and a plan to protect your kidneys. Always follow your provider’s advice for your situation.
When is surgery considered?
This topic is about getting a urine test, not surgery itself. However, if a urine test shows a serious problem before a planned surgery, your surgery might be postponed until the issue is treated.
Living with this condition
Most people only need a urine test on the day of a procedure. Following the preparation tips helps ensure a smooth experience. After the test, you can return to your normal activities unless your healthcare team advises otherwise.
Lifestyle tips
- Stay well hydrated every day to keep your urine clear and your kidneys healthy
- Use good bathroom hygiene to reduce the chance of infections
- Tell your doctor about any new medicines or supplements you take
Diet and exercise
A healthy diet and regular exercise help your whole body, including your kidneys. Water is best. Avoid too much salt, sugar, and processed foods. No special diet is needed for just a urine test.
Mental health and emotional wellbeing
Feeling anxious about a test is normal. Talking to a nurse or doctor about your worry can help. Deep breathing or listening to calming music before the test may also ease your nerves.
Prevention
You can help prevent a contaminated urine sample by following the clean catch steps carefully. If you have a urinary tract infection, proper hygiene and staying hydrated may reduce your risk. But some conditions that require a test are not preventable.
Screening programmes
Routine urine tests are sometimes done as part of a health check-up. Your doctor will tell you if you need one.
Complications
If left untreated
- A contaminated sample may lead to an incorrect diagnosis and unnecessary treatment
- If you have an infection and it is not treated, it can spread to your kidneys
- Delaying a needed test could mean missing a health problem
Long-term outlook
Most urine tests go smoothly and give helpful information. If you follow the simple preparation steps, you are doing your best to get a clear result. Your healthcare team is there to support you.
