Urine testing
Urine test Plymouth
A urine test Plymouth screens for infections, kidney disease, diabetes, and other urinary tract abnormalities. At Tamar Health, we perform comprehensive urinalysis using a urine dipstick that tests for protein, blood (haematuria), leucocytes (white blood cells), nitrites, glucose, ketones, specific gravity, and pH. If infection is suspected, we can also arrange mid-stream urine (MSU) culture and sensitivity testing to identify the bacteria causing infection and determine which antibiotics will work best. A simple urine test can reveal important health information and guide appropriate treatment.
Why urine testing is important
Urine tests are one of the most useful screening tools in medicine. Abnormalities in urine often indicate treatable conditions — urinary tract infections, kidney disease, diabetes, and bladder disorders can all be detected through urinalysis. For women, urinary tract infections are extremely common, and many require antibiotic treatment. A urine culture identifies the specific bacteria and provides antibiotic sensitivities so your doctor can prescribe the right medication. Blood or protein in urine can indicate kidney disease, diabetes complications, or other serious conditions requiring investigation. Glucose in urine may suggest diabetes. A simple urine test, collected easily during your appointment, can prompt early diagnosis and treatment of important health conditions.
What this test measures
Urinalysis includes immediate dipstick testing and, if infection is suspected, culture of the urine to identify bacteria and determine antibiotic sensitivities. The dipstick measures multiple parameters in a single test.
| Test component | What it measures | Why it matters |
|---|---|---|
| Protein | Protein in the urine | Normally absent; presence suggests kidney disease, infection, or glomerulonephritis |
| Blood (haematuria) | Red blood cells in the urine | Can indicate infection, kidney stones, kidney disease, or bladder/prostate issues |
| Leucocytes | White blood cells in the urine | Suggests urinary tract infection or inflammation |
| Nitrites | Nitrite compounds produced by bacteria | Highly specific for bacterial UTI; nitrites present indicate likely infection |
| Glucose | Glucose in the urine | Normally absent; presence suggests diabetes or very high blood glucose |
| Ketones | Ketone bodies in the urine | Suggests uncontrolled diabetes or severe calorie restriction |
| Specific gravity | Concentration of the urine | Indicates hydration status; very concentrated or dilute urine may affect test interpretation |
| pH | Acidity or alkalinity of urine | Alkaline urine favours certain bacterial infections; abnormal pH suggests kidney or metabolic issues |
| Urine culture (if ordered) | Bacterial growth and identification | Identifies specific bacteria causing infection and provides antibiotic sensitivities for targeted treatment |
Who should get this test?
Urine testing is recommended if you have symptoms suggesting urinary tract infection — such as burning or pain on urination, urinary frequency or urgency, or cloudy/foul-smelling urine. It’s also appropriate for anyone with blood in urine, kidney concerns, symptoms of diabetes, or pre-operative assessment before surgery. Women with recurrent UTIs benefit from testing to identify the bacteria and guide treatment. Anyone with chronic kidney disease, diabetes, or high blood pressure should have periodic urine screening to monitor for proteinuria (protein in urine). General health checks often include urine dipstick testing as a baseline screen.

What your results mean
Understanding your urine test results
Normal urine should be clear to pale yellow and contain no protein, blood, white cells, or glucose. If your dipstick shows leucocytes and nitrites, this strongly suggests a bacterial UTI, and antibiotics are usually appropriate. A positive urine culture confirms the diagnosis and identifies which bacteria are responsible, allowing your doctor to prescribe the most effective antibiotic. If leucocytes are present but nitrites are absent, infection is less likely but still possible — or you may have early infection before nitrites develop. Protein in urine, especially if accompanied by blood, suggests kidney disease or glomerulonephritis requiring further investigation. Glucose in urine may indicate uncontrolled diabetes or very high blood glucose levels.
If infection is suspected, a urine culture is crucial because it tells us which antibiotic will work best — not all antibiotics are effective against all bacteria. The culture also measures bacterial load (how many bacteria are present) and provides sensitivities showing which antibiotics the bacteria responds to. This prevents unnecessary broad-spectrum antibiotic use and reduces the risk of developing antibiotic resistance. Our clinician will review your results and advise whether antibiotics are needed and which type is most appropriate.
What happens at your appointment
When you attend your urine test appointment at Tamar Health in Estover, you’ll be asked to provide a mid-stream urine (MSU) sample in a clean container. If you’re collecting the sample before your appointment, bring it in a sterile container (which we can provide). A fresh sample is best, ideally collected within 2 hours of testing. Our staff will perform immediate dipstick analysis while you wait — this gives results in just a few minutes and lets us know if infection is likely.
If a urine culture is needed (usually if infection is suspected), your sample will be sent to the laboratory where bacteria are grown and identified. Culture results typically come back within 24–72 hours, depending on the organism. Once culture results are available, we’ll contact you with the diagnosis and antibiotic recommendations if needed. If your dipstick is normal and no culture is needed, you may get your full results immediately. Our clinician can discuss your results and advise on next steps — whether that’s antibiotics for confirmed infection, lifestyle advice for recurrent UTIs, or GP referral for investigation of other abnormalities like blood or protein in urine.
Frequently asked questions
What’s the best way to collect a mid-stream urine sample?
For a mid-stream urine (MSU) sample: wash your hands and external genital area with water (not antiseptic which can affect results). Begin urinating into the toilet, then catch the middle portion of the stream in a clean container. You don’t need to finish urinating in the container — just collect the middle stream. Stop before the end of urination. Provide the sample in a clean, preferably sterile container. If you cannot provide a fresh sample at home, we have sterile containers at the clinic.
Can I still have a urine test if I’m menstruating?
Yes, you can have a urine test while menstruating, but blood from menstruation may contaminate the sample and make results harder to interpret. For most accurate results, it’s preferable to test a few days after your period ends. However, if you have urgent UTI symptoms, don’t delay testing — just let our staff know you’re menstruating so they can interpret results appropriately.
Do I need antibiotics if my urine shows white cells but the culture is negative?
A negative culture with leucocytes in urine suggests the sample may have been contaminated, or you may have early-stage infection before bacteria fully develop, or possibly non-infectious urethritis (inflammation without bacterial infection). Our clinician will consider your symptoms and may recommend retesting, watchful waiting, or investigation of other causes. Not all urinary symptoms are due to infection.
What causes recurrent urinary tract infections?
Recurrent UTIs are common, especially in women, and can be caused by anatomical factors, incomplete bladder emptying, constipation, dehydration, sexual activity, or use of spermicides. Preventive measures include ensuring adequate hydration, complete bladder emptying, and regular urination. Some people benefit from cranberry supplements, probiotics, or post-coital urination. Our clinician can discuss prevention strategies specific to your situation.
What if my urine shows blood but no infection?
Blood in urine without infection (sterile haematuria) warrants investigation to rule out kidney stones, kidney disease, or bladder/prostate issues. Your GP can arrange imaging (ultrasound or CT) and further blood tests to investigate. Any episode of blood in urine should be discussed with your doctor, even if it’s a one-off occurrence.
